Create a side panel

The Side Panel API allows extensions to display their own UI in a Chrome side panel. The side panel remains open when navigating between tabs, if set to do so. You can also restrict its use to specific websites.

The Dictionary side panel example allows users to right-click on a word and see the definition in the side panel.

For more samples and use cases, see the Side Panel API reference page.
