Add the rich text editor control to a model-driven app

The rich text editor control is a lightweight, HTML-based editor that's built on the popular CKEditor. It lets you create, paste, and edit formatted text in your model-driven apps. To format text in the editor, you can use the editor toolbar, insert HTML tags, or paste formatted text from other applications, like a web browser or Word.

You can customize the editor's appearance, features, and behavior. The control's default configuration is shown in the following screenshot.

Add the rich text editor control to a text column

When you format a text column as rich text, the default rich text editor control is added automatically.

1. Sign in to Power Apps.

2. In the left navigation pane, select Solutions.

3. Open a solution and a table in the solution.

4. In the Columns and data area, select a text column.

   If the table doesn't contain a text column, select + (New column) and enter a name for the column.

5. In Data type, select > to the right of Text, and then select the appropriate Rich text option based on whether the column contains a single line of text or multiple lines.

6. Save the column, and then add it to a form.

Add the rich text editor control to a text column in a form

1. Sign in to Power Apps.

2. In the left navigation pane, select Solutions.

3. Open a solution and a table in the solution.

4. In the Data experiences area, select Forms, and then find the form that contains the text column you want to add the rich text editor to.

5. Select ⋮ > Edit > Edit in new tab.

6. On the form designer canvas, select, add, or create a text column.

7. In the column properties pane, expand the Components list, select + Component, and then select Rich Text Editor Control.

8. In the Add Rich Text Editor Control pane, select Web, Phone, and Tablet to allow apps running on any device to use the editor.

   If you want to customize the editor, enter the relative URL of its configuration file, a JavaScript web resource that contains the properties you want to change, in the Static value box. If you leave this field empty, the editor uses its default configuration.

9. Select Done.

10. Select Save and publish to apply your changes to the form.

Customize the rich text editor control

Power Apps allows you to change the properties of the rich text editor control to customize its appearance, features, and behavior. To customize a specific instance of the control, specify properties and their values in an individual JSON-formatted configuration file. To customize the control's global configuration, change the properties in the default configuration file.

Levels of customization

Up to three levels, or layers, of configuration can be applied to customize the rich text editor:

1. At the most fundamental level, every instance of the control takes its configuration from the file RTEGlobalConfiguration_Readonly.json. The file is read-only, so you can't change these properties directly.
2. At the next level, every instance of the control takes its configuration from the properties in the file RTEGlobalConfiguration.json, if any are present. This configuration is layered on top of the previous one, so the properties in this file replace the same named properties in the read-only file.
3. Finally, at the highest level, a specific instance of the control takes its configuration from a specific configuration file, if one exists. This configuration is layered on top of the previous one, so the properties in this file replace the same named properties in the two lower-level files.

We have to add a slight qualification here. Not all properties are replaced by those in a higher-level configuration. The extraPlugins properties are merged to allow the use of a wide range of external and out-of-the-box plug-ins in the default configuration. That lets you activate and deactivate plug-ins as needed in the configuration file for specific instances of the control.

Customize a specific instance of the rich text editor

1. In Visual Studio Code or other text editor, create a file and give it a meaningful name.

   The file RTEGlobalConfiguration.json contains the rich text editor's default, or global, configuration. If you're customizing the control in, say, a contact form, you might name the file something like RTEContactFormConfiguration.json.

2. Copy and paste the following code snippet in the file:

   {
   "defaultSupportedProps": {
     "propertyName": "value",
     "propertyName": "value",
     "propertyName": "value"
   },
   }
   

   Note that the last propertyName:value pair doesn't end with a comma.

3. Replace propertyName and value with the rich text editor control properties you want to change. String values must be enclosed in quotation marks.

   We've provided a few example configurations for you, but you can define others to suit your needs.

4. In Power Apps, create a JavaScript (JS) type web resource using the JSON file you created in step 1.

5. Add the rich text editor control to a text column in a form and in the Add Rich Text Editor Control pane > Static value, enter the relative URL of the JavaScript web resource.

   Although you may enter the absolute URL of the web resource, we recommend you enter the relative URL. That way, the web resource still works if you import it as a solution into a different environment, provided the relative path is the same.

   For example, if the URL of the web resource is https://yourorg.crm.dynamics.com/WebResources/rtecontactform, the relative URL is /WebResources/rtecontactform.

6. Select Done.

7. Select Save and publish to apply your changes to the form.

Customize the rich text editor globally

The editable global configuration file RTEGlobalConfiguration.json is the second level of customization you can apply. By default, the file is empty. That means that all instances of the rich text editor use the properties in the read-only file RTEGlobalConfiguration_Readonly.json, unless you create a configuration file for a specific instance of the control.

If your business needs require you to customize the control everywhere, specify the values you need in the RTEGlobalConfiguration.json file. Use the read-only file as an example to make sure you enter property-value pairs in the right format.

Use Copilot to refine text in the editor

Copilot uses natural language processing algorithms to help improve written content. You can add Copilot to the rich text editor and then get suggestions to improve the grammar, clarity, or overall quality of your text. Learn how to use Copilot in the rich text editor.

Rich text editor properties

The JSON file that determines the "look and feel" of an instance of the rich text editor contains two sets of properties:

• The defaultSupportedProps section contains properties of plug-ins that determine what the control can do. You're not limited to the properties of CKEditor and its plug-ins. You can also set values for properties of plug-ins that you add or create.
• The individual properties section contains properties that determine what the control looks like.

Example configuration file

The following code is an example of a JSON file that contains both defaultSupportedProps properties and individual configuration properties. If a property has a default value, the default value is shown. If a property doesn't have a default value, a sample value is shown to illustrate the syntax. The properties are described in the two tables that follow.

defaultSupportedProps

The following table describes the most commonly used properties, but you can configure all the properties that CKEditor supports. The rich text editor control uses CKEditor 4.

Property	Description	Default value
height	Sets the initial height of the content area, in pixels.	"185"
stickyStyle	Sets the editor font and size.	See defaultSupportedProps
stickyStyles_defaultTag	Creates a wrapper around the text in the editor content area. It's initially set to "div," but you can change it to "p" or any alternate tag.	"div"
font_defaultLabel	Sets the font label that's displayed in the toolbar. The label is for appearance only and isn't functional. The stickyStyle property determines the editor font and size.	"Segoe UI"
fontSize_defaultLabel	Sets the font size label that's displayed in the toolbar. The label is for appearance only and isn't functional. The stickyStyle property determines the editor font and size.	"9"
toolbarLocation	Sets the location of the toolbar in the editor content area. Supported values are "top" and "bottom."	"bottom"
toolbar	Lists the toolbar buttons to display.	See defaultSupportedProps
plugins	Lists preset plug-ins that the editor can use. The plug-ins in this list might be different from the plug-ins that are loaded, if extraPlugins and removePlugins are given a value. If you set this property to an empty string, the editor loads without the toolbar.	See defaultSupportedProps
extraPlugins	Appends plug-ins to the plugins list to load more plug-ins. Many plug-ins require other plug-ins to work. The rich text editor automatically adds them, and you can't use this property to override them. Use removePlugins instead.	See defaultSupportedProps
removePlugins	Lists plug-ins not to load. Use it to change which plug-ins are loaded without changing the plugins and extraPlugins lists.	See defaultSupportedProps
superimageImageMaxSize	Sets the maximum size in megabytes (MB) allowed for embedded images when using the superimage plug-in.	"5"
disallowedContent	Lets you prevent users from inserting elements that you don't want to have in your content. You can disallow entire elements or by attributes, classes, and styles.	See defaultSupportedProps
linkTargets	Allows you to configure which link target options are available for users when they create links: - "notSet": No target set - "frame": Opens the document in the specified frame - popupWindow": Opens the document in a popup window - "_blank": Opens the document in a new window or tab - "_top": Opens the document in the full body of the window - "_self": Opens the document in the same window or tab where the link is activated - "_parent": Opens the document in the parent frame	"notSet", "_blank"

Individual properties

The following table describes more properties you can use to customize the rich text editor control.

Property	Description	Default value
attachmentEntity	To enforce more security on uploaded files by using a table other than the default, set this property and specify a different table. Syntax: "name": "tableName", "fileAttributeName": "attributeNameofBlobReference"	See defaultSupportedProps
disableContentSanitization	Content sanitization removes some custom attributes or tags from rich text content. It's disabled by default to allow copying and pasting of rich text content from external sources. This property applies only to edit mode. When the editor control is read-only or disabled, content is always sanitized.	true
disableDefaultImageProcessing	By default, images that are inserted in the editor are uploaded to the attachmentEntity defined in the configuration. External users might lack privileges to view the content in the table. Instead, set this property to true to store images as base64 strings directly in the column that's configured to use the rich text editor control.	false
disableImages	Determines whether images can be inserted in the editor. This property has highest priority. When this property is set to true, images are disabled, regardless of the value of the imageEntity property.	false
externalPlugins	Lists external plug-ins or plug-ins that you create that can be used in the rich text editor control. Syntax: "name": "pluginName", "path": "pathToPlugin" (the path value can be an absolute or relative URL)	None; see defaultSupportedProps for an example
imageEntity	To enforce more security on images by using a table other than the default, set this property and specify a different table. Syntax: "imageEntityName": "tableName", "imageFileAttributeName": "attributeNameofBlobReference"	See defaultSupportedProps
readOnlySettings	These properties determine the behavior of the column when it's viewed in a read-only or disabled state. You can specify any supported property.	None; see defaultSupportedProps for an example
sanitizerAllowlist	Lists other kinds of content that can be displayed in the editor.	See defaultSupportedProps
showAsTabControl	Allows you to display more commands above the content area. Must be set to true to use the following properties: showFullScreenExpander, showHtml, showPreview, showPreviewHeaderWarning	false
showFullScreenExpander	Determines whether the editor can be used in full-screen mode. showAsTabControl must be set to true.	false
showHtml	Allows users to display and edit the HTML content directly. showAsTabControl must be set to true.	false
showPreview	Allows users to preview the editor content rendered as HTML. showAsTabControl must be set to true.	false
showPreviewHeaderWarning	Allows you to show or hide the warning message that's displayed when previewing content. showAsTabControl and showPreview must be set to true.	false
allowSameOriginSandbox	Allows the content in the editor to be treated as from the same origin as the rendering app. Use this property with caution. Only use trusted external content. When this property is set to true, any external content could have access to internal resources.	false

Example configurations

The following sample configurations create specific customizations of the rich text editor. You can use them as-is or as a jumping-off point to customize a specific instance of the rich text editor or globally.

Set the default font to 11-point Calibri

Set these defaultSupportedProps properties in your configuration file. Each value except the last one should be followed by a comma (,).

"font_defaultLabel": "Calibri",
"fontSize_defaultLabel": "11",
"stickyStyle": {
  "font-size": "11pt",
  "font-family": "Calibri/Calibri, Helvetica, sans-serif;"
},

Make the Enter key insert a new line instead of a paragraph block

By default, pressing the Enter key creates a paragraph block with the <p> HTML tag. HTML uses paragraph blocks to group information, like paragraphs in a Word document. Browsers can format the <p> tag slightly differently, so for visual consistency, you might want to use the new line or line break tag <br\> tag instead.

Set this defaultSupportedProps property in your configuration file. Follow this value with a comma (,) unless it's the last property in the file.

"enterMode": 2,

Paste or create HTML 5 content only

Although the rich text editor control works best with HTML 5 content, you can use HTML 4 tags. In some cases, however, mixing HTML 4 and HTML 5 tags can create usability challenges. To make sure all content is HTML 5, provide all the supported HTML 5 tags in the allowedContent property. The editor control converts any noncompliant tags to their HTML 5 equivalent.

Set this defaultSupportedProps property in your configuration file. Follow this value with a comma (,) unless it's the last property in the file.

"allowedContent": "a(*)[*]{*};abbr(*)[*]{*};address(*)[*]{*};area(*)[*]{*};article(*)[*]{*};aside(*)[*]{*};audio(*)[*]{*};b(*)[*]{*};base(*)[*]{*};bdi(*)[*]{*};bdo(*)[*]{*};blockquote(*)[*]{*};body(*)[*]{*};br(*)[*]{*};button(*)[*]{*};canvas(*)[*]{*};caption(*)[*]{*};cite(*)[*]{*};code(*)[*]{*};col(*)[*]{*};colgroup(*)[*]{*};data(*)[*]{*};datalist(*)[*]{*};dd(*)[*]{*};del(*)[*]{*};details(*)[*]{*};dfn(*)[*]{*};dialog(*)[*]{*};div(*)[*]{*};dl(*)[*]{*};dt(*)[*]{*};em(*)[*]{*};embed(*)[*]{*};fieldset(*)[*]{*};figcaption(*)[*]{*};figure(*)[*]{*};footer(*)[*]{*};form(*)[*]{*};h1(*)[*]{*};h2(*)[*]{*};h3(*)[*]{*};h4(*)[*]{*};h5(*)[*]{*};h6(*)[*]{*};head(*)[*]{*};header(*)[*]{*};hr(*)[*]{*};html(*)[*]{*};i(*)[*]{*};iframe(*)[*]{*};img(*)[*]{*};input(*)[*]{*};ins(*)[*]{*};kbd(*)[*]{*};label(*)[*]{*};legend(*)[*]{*};li(*)[*]{*};link(*)[*]{*};main(*)[*]{*};map(*)[*]{*};mark(*)[*]{*};meta(*)[*]{*};meter(*)[*]{*};nav(*)[*]{*};noscript(*)[*]{*};object(*)[*]{*};ol(*)[*]{*};optgroup(*)[*]{*};option(*)[*]{*};output(*)[*]{*};p(*)[*]{*};param(*)[*]{*};picture(*)[*]{*};pre(*)[*]{*};progress(*)[*]{*};q(*)[*]{*};rp(*)[*]{*};rt(*)[*]{*};ruby(*)[*]{*};s(*)[*]{*};samp(*)[*]{*};section(*)[*]{*};select(*)[*]{*};small(*)[*]{*};source(*)[*]{*};span(*)[*]{*};strong(*)[*]{*};style(*)[*]{*};sub(*)[*]{*};summary(*)[*]{*};sup(*)[*]{*};svg(*)[*]{*};table(*)[*]{*};tbody(*)[*]{*};td(*)[*]{*};template(*)[*]{*};textarea(*)[*]{*};tfoot(*)[*]{*};th(*)[*]{*};thead(*)[*]{*};time(*)[*]{*};title(*)[*]{*};tr(*)[*]{*};track(*)[*]{*};u(*)[*]{*};ul(*)[*]{*};var(*)[*]{*};video(*)[*]{*};wbr(*)[*]{*};",

Paste or create plain text only

Set these defaultSupportedProps properties in your configuration file. Each value except the last one should be followed by a comma (,).

"enterMode": 2,
"shiftEnterMode": 2,
"allowedContent": "*",
"disallowedContent": "*",
"forcePasteAsPlainText": true,
"toolbar": [],
"removePlugins": "contextmenu,liststyle,openlink,tableresize,tableselection,tabletools",

Set this individual property in your configuration file. Follow this value with a comma (,) unless it's the last property in the file.

"disableImages": true,

Allow the editor to use the full screen

Set these individual properties in your configuration file. Each value except the last one should be followed by a comma (,).

"showAsTabControl": true,
"showFullScreenExpander": true,

Allow viewing and editing HTML content

To allow users to view and edit the HTML of their content directly, show the HTML tab.

Set these individual properties in your configuration file. Each value except the last one should be followed by a comma (,).

"showAsTabControl": true,
"showHtml": true,

Show a simplified toolbar or remove it entirely

By default, the editor toolbar contains all the available formatting tools. To provide a simplified toolbar, use the toolbar property and specify the tools that users can use to format their content.

Set this defaultSupportedProps property in your configuration file. Follow this value with a comma (,) unless it's the last property in the file.

"toolbar": [ { "items": [ "FontSize", "Bold", "Italic", "Underline", "BGColor" ] } ],

To remove the toolbar entirely, set the value of toolbar to '[]' (two square brackets).

Add a new font list and set 20-pixel Brush Script MT as the default font

Set these defaultSupportedProps properties in your configuration file. Each value except the last one should be followed by a comma (,).

"font_names": "Brush Script MT/'Brush Script MT', cursive;Calibri/Calibri, Helvetica, sans-serif;Calibri Light/'Calibri Light', 'Helvetica Light', sans-serif;"
"font_defaultLabel": "Brush Script MT"
"fontSize_sizes": "8/8px;12/12px;20/20px;32/32px"
"fontSize_defaultLabel": "20"
"stickyStyle": {
  "font-size": "20px",
  "font-family": "'Brush Script MT', cursive"
},

Position the toolbar at the top of the rich text editor

Set this defaultSupportedProps property in your configuration file. Follow this value with a comma (,) unless it's the last property in the file.

"toolbarLocation": "top",

Start the editor at 30 pixels high and grow to fit content

Set these defaultSupportedProps properties in your configuration file. Each value except the last one should be followed by a comma (,).

"autoGrow_onStartup": false,
"autoGrow_maxHeight": 0,
"autoGrow_minHeight": 30,
"height": 30,

Fix the height of the editor at 500 pixels

Set these defaultSupportedProps properties in your configuration file. Each value except the last one should be followed by a comma (,).

"removePlugins": [ "autogrow" ],
"height": 500,

Make the context (right-click) menu use the browser's default context menu

To replace the editor control's context menu with the browser's default context menu, remove the contextmenu plug-in.

Set this defaultSupportedProps property in your configuration file. Follow this value with a comma (,) unless it's the last property in the file.

"removePlugins": "contextmenu,liststyle,openlink,tableresize,tableselection,tabletools",

Find the configuration of a rich text editor control

If you're not sure where the configuration of an instance of the rich text editor is coming from, you can find it using your browser's developer tools.

1. In Microsoft Edge or Google Chrome, run your model-driven app and open a form that has the rich text editor control.
2. Right-click the rich text editor content area and select Inspect.
3. In the inspection pane, select the Console tab.
4. Select the parent Main.aspx page in the list box on the command bar.

1. Select the Clear console icon on the inspection pane command bar, and then enter CKEDITOR.config. in the console.

1. In the inspection pane console, enter CKEDITOR.config. to display the different configurations.

1. Select a configuration, such as autoGrow_minHeight, to display the current setting.

The rich text editor toolbar

The following table describes the formatting tools that are available in the rich text editor by default.

Icon	Name	Shortcut key	Description
	Copy Formatting	Ctrl+Shift+C, Ctrl+Shift+V	Apply the look of a particular section to another section.
	Font Name	Ctrl+Shift+F	Select a font. The application considers the font that you select the default font. Segoe UI is the default font if you don't select one. When you select formatted content, the name of the font that's applied to it is displayed. If your selection contains multiple fonts, the first one applied to the selection is displayed.
	Font Size	Ctrl+Shift+P	Change the size of your text. The application considers the font size that you select the default size. 12 is the default size if you don't select one. When you select formatted content, the font size that's applied to it is displayed. If your selection contains multiple sizes, the first one applied to the selection is displayed.
	Bold	Ctrl+B	Make your text bold.
	Italic	Ctrl+I	Italicize your text.
	Underline	Ctrl+U	Underline your text.
	Background Color		Make your text stand out by highlighting it in a bright color.
	Text Color		Change the color of your text.
	Insert/Remove Bulleted List		Create a bulleted list.
	Insert/Remove Numbered List		Create a numbered list.
	Decrease Indent		Move your paragraph closer to the margin.
	Increase Indent		Move your paragraph farther away from the margin.
	Block Quote		Apply a block-level quotation format to your content.
	Align Left	Ctrl+L	Align your content with the left margin.
	Align Center	Ctrl+E	Center your content on the page.
	Align Right	Ctrl+R	Align your content with the right margin.
	Link		Create a link in your document for quick access to web pages and other cloud resources. Enter or paste the anchor text in the Display Text box, and then enter or paste the URL in the URL box. Optionally, select a Link Type and protocol if the link is to something other than a web page. To specify where a URL-type link should open, select the Target tab and then select a Target. A pasted or typed URL is automatically converted into a link. For example, http://myexample.com becomes <a href="http://myexample.com">http://myexample.com</a>.
	Unlink		Remove the link from an anchor and make it plain text.
	Superscript		Type small letters just above the line of text.
	Subscript		Type small letters just below the line of text.
	Strikethrough		Cross out text by drawing a line through it.
	Image		To insert an image, paste it from your clipboard into the content area or drag an image file from a folder to the content area. Drag any corner of the image to resize it. The control supports .png, .jpg., and .gif images. To have more control over the image's source, appearance, and behavior, select the Image button. Browse to the image file in a local folder or enter its URL. If the image is stored on an external server, enter the absolute path. If it's on a local server, you can enter a relative path. Optionally, enter a specific height and width to resize the image, and select an alignment. You should also enter alt text to describe the image for people who use screen readers. If the image is also a link to a web page or other cloud resource, enter the URL of the resource in the Target URL box and, if needed, select the Target where the link should open.
	Text direction from left to right		Change the text to left-to-right. This is the default setting.
	Text direction from right to left		Change the text to right-to-left for bi-directional language content.
	Undo		Reverse the last change you made to the content.
	Redo		Undo your last undo, or reapply the last change you made to the content.
	Remove Format		Remove all formatting from the select text.
	Table		Insert a table with the number of rows and columns you select. To have more control over the table's size and appearance, select the Table button > More and change its properties. You can also right-click a table to view and change its properties. To change the width of a column, drag its border. You can select one or more cells, rows, or columns and apply specific formatting, add a link to selected text, and cut, copy, and paste entire rows or columns.
	Personalization Settings		Set your default font and font size.
	Accessibility Help	Alt+0	Open the list of keyboard shortcuts you can use in the rich text editor.
	Expand Toolbar		When the window is too narrow to show the entire toolbar, select to expand the toolbar to a second row.

Tip

To use your browser's built-in spell checker, press the Ctrl key as you right-click the text you want to check. Otherwise, the right-click (context) menu provides contextual formatting for the element you select.
An alternative to your browser's built-in spell checker is the Microsoft Editor browser extension. Microsoft Editor works seamlessly with the rich text editor control, and when enabled, provides fast and easy inline grammar and spell-check capabilities.

Use the rich text editor offline

The rich text editor control is available when you're working offline, although without some of the features and functionality you're used to. Images that you upload using the editor's default configuration aren't available when you're working offline.

The following plug-ins are available to the rich text editor when it's offline:

• ajax, autogrow, basicstyles, bidi, blockquote, button, confighelper, contextmenu, dialog, dialogui, editorplaceholder, enterkey, entities, fakeobjects, floatingspace, floatpanel, format, horizontalrule, htmlwriter, indent, indentblock, indentlist, justify, lineutils, list, listblock, maximize, menu, menubutton, notification, notificationaggregator, panel, panelbutton, popup, preview, removeformat, resize, richcombo, selectall, showborders, sourcearea, specialchar, stylescombo, tab, textmatch, textwatcher, toolbar, undo, widgetselection, wysiwygarea, xml

The following formatting tools are available in the rich text editor when it's offline:

• Bold, italic, underline, bulleted and numbered lists, decrease and increase indent, block quote, align left, align center, align right, strikethrough, bi-directional text, undo and redo, and remove formatting

Best practices for using the rich text editor

• Rich text fields store HTML tags for formatting along with user-entered data. When you set the maximum size of rich text fields, make sure to allow for both the HTML tags and the user's data.

• For the best performance, keep your HTML content to 1 MB or less. At larger sizes, you may notice slower response times for loading and editing.

• In the default configuration, images don't negatively affect performance because they're stored separately from the HTML content. However, images are stored as base64 content in the text column when the user who uploads them doesn't have permissions on the msdyn_richtextfiles table. Base64 content is large, so you generally don't want to store images as part of the column content.

• If you have a system administrator or basic user security role, the user personalization feature works by default. If you don't have these roles, you must have create, read, and write privileges on the msdyn_customcontrolextendedsettings table for the user personalization plug-in to work.

Frequently asked questions
