At any time, you can see all of the hidden widgets on a page by clicking the Unhide Elements icon at the bottom of the left panel under Settings.
Note
The Unhide Elements icon only displays if you have hidden elements in your site.
To unhide elements:
Click the hidden element in the editor.
In the left panel, click Unhide Element icon. Hidden elements are now displayed.
Once hidden elements are displayed, to restore them, click on the element, and then click Yes on the message.
Note
If you are using the unhide element feature and it does not reveal an image on your site, your image might need to be added and uploaded.
