# [Extensions] - Use Sidebar Extensions in Entries

This page explains how to use a Sidebar Extension within entries for selected content types in a Contentstack stack. It is intended for developers and content managers who have already added a Sidebar Extension and need to run it from the entry sidebar while authoring content.

## Use Sidebar Extensions in Entries

**Note**: Experience Extensions use the legacy approach with extensions. We recommend using the  [Sidebar UI Location](/docs/developers/developer-hub/sidebar-location/) for the Contentstack App Framework to extend the functionality of your apps.

Once you have added a [Sidebar Extension](/docs/developers/create-sidebar-extensions/about-sidebar-extensions/) in your [stack](/docs/developers/set-up-stack/about-stack), you can use it in the [entries](/docs/content-managers/author-content/about-entries/) of selected [content type(s)](/docs/developers/create-content-types/about-content-types).

To use Sidebar Extensions in an entry, log in to your [Contentstack account](https://www.contentstack.com/login/), and perform the following steps:
- In your stack, click on the “Entries” icon on the left navigation panel.
- Select the content type for which you have enabled the Sidebar Extension.
- [Create an entry](/docs/content-managers/author-content/create-an-entry/), click on the "Sidebar Extensions"** **icon located on the right panel. Select the Sidebar Extension that you want to add to the entry from the drop-down menu.
- Then, the selected Sidebar Extension will expand in the sidebar. Run it to see the results.

Once done using the Sidebar Extension, click on the close (x) button.
