Custom Sidebar

This article explains how to customize the appearance of the sidebar next to an entry in the Contentful web app.


The sidebar defines the main editing context when working with content. The sidebar has a default appearance and it can be replaced with a custom list of built-in widgets or UI Extensions. The sidebar is:

  • configured on a content type level and stored in its editor_interface
  • a curated list of built-in widgets and UI Extensions
  • each widget and UI Extension can only be used once per sidebar
  • supports setting configuration parameters for UI Extensions

Default sidebar

The default sidebar is the initial state for all content type and it consists of six built-in widgets. Those are:

  • Status: Changes the status of an entry
  • Preview: Connects content to a custom preview application
  • Links: Lists all incoming links to the current entry
  • Translations: Toggles which locales to show
  • Versions: Access to the snapshots of an entry
  • Users: Other users currently active on the same entry

Creating a custom sidebar
