You can hide a widget so that it does not display on a page.
You must be the page owner or an editor of the page to hide a widget.
A hidden widget is fully functional but does not display on a page. Typically, you hide widgets such as the Script Adapter widget, which, instead of displaying business data, transforms the data so that another widget can use it.
A hidden widget is in hidden content area. When you are editing the page, you can open this area to see the widgets that it contains and edit the hidden widgets to change their settings and wire them to other widgets, for example.
