ContextMenu control.

Description

A contextual menu (ContextMenu) is a list of commands that are based on the context of selection, mouse hover, or keyboard focus. They're one of the most effective and highly used command surfaces, and can be used in various places.

This code component provides a wrapper around the Fluent UI ContextualMenu control bound to a button for use in canvas apps and custom pages.

Properties

Key Properties

Property Description
Items The action items to render. The first item is considered the root item.

Items Properties

Name Description
ItemDisplayName The Display Name of the menu item.
ItemKey The key to use to indicate which item is selected, and when adding sub items. The keys must be unique.
ItemEnabled Set to false if the option is disabled.
ItemVisible Set to false if the option is not visible.
ItemChecked Set to true if the option is checked.
ItemIconName The Fluent UI icon to use (see Fluent UI icons)
ItemIconColor The color to render the icon as (e.g. named, rgb or hex value).
ItemIconOnly Do not show the text label - only the icon.
ItemHeader Render the item as a section header. If there are items that have their ItemParentKey set to the key of this item, then they are added as semantically grouped items under this section.
ItemTopDivider Render a divider at the top of the section.
ItemDivider Render the item as a section divider - or if the item is a header (ItemHeader = true), then controls whether to render a divider at the bottom of the section.
ItemParentKey Render the option as child item of another option.

Note

  • ItemIconColor will override the component's Theme value and ignore other state colors (e.g., disabled).
  • ItemHeader and ItemDivider must be set to true to render as a divider. If set to false, it expects other values and will render blank.

Example

Example Power Fx formula for Items:

  Table(
      {
          ItemKey: "File",
          ItemIconName: "save",
          ItemDisplayName: "Save",
          ItemOverflow:true
      },
       {
          ItemKey: "Delete",
          ItemIconName: "Delete",
          ItemDisplayName: "Delete",
          ItemOverflow:true
      }
  )

Event Properties

Property Description
InputEvent An event to send to the control. E.g. SetFocus. See below.

Behavior

Supports SetFocus as an InputEvent.

Configure 'On Select' behavior

Use the Switch() formula in the component's OnSelect property to configure specific actions for each item by referring to the control's selected ItemKey as the switch value.

Replace the false values with appropriate expressions in the Power Fx language.

  Switch( Self.Selected.ItemKey,
    /* Action for ItemKey 1 */
    "File", false,
    
    /* Action for ItemKey 2 */
    "Delete", false,
  
    /* Default action */
        false
  )

Setting Focus on the control

When a new dialog is shown, and the default focus should be on the control, an explicit set focus will be needed.

To make calls to the input event, you can set a context variable that is bound to the Input Event property to a string that starts with SetFocus and followed by a random element to ensure that the app detects it as a change.

E.g.

UpdateContext({ctxResizableTextareaEvent:"SetFocus" & Text(Rand())}));

The context variable ctxResizableTextareaEvent would then be bound to the property Input Event property.

Limitations

This code component can only be used in canvas apps and custom pages.
