Custom actions in the SharePoint Add-in model


The approach you take to modify list item menus and the ribbon in SharePoint is different in the new SharePoint Add-in model than it was with Full Trust Code. In a typical Full Trust Code (FTC) / Farm Solution scenario, list item menus and ribbon modifications were defined in XML (custom actions), packaged in features, and deployed via SharePoint Solutions.

In an SharePoint Add-in model scenario, you use the SharePoint Client-side Object Model (CSOM) or REST API to create custom actions that modify list item menus and the ribbon. This pattern is commonly referred to as the remote provisioning pattern.

High-level guidelines

As a rule of a thumb, we would like to provide the following high-level guidelines for creating and deploying custom actions in the new SharePoint Add-in model.

Getting started

The following sample demonstrates how to add a custom action to the site settings menu in the host web, how to show a dialog in a custom action, how to hide a dialog that hosts a page from a remote add-in web, and how to use a custom action to create lists and set the theme of a web.
