A storefront widget is a JavaScript component that handles the behavior of a content type after Page Builder renders it on the storefront. For example, the Tabs and Sliders have their own storefront widgets to handle the end-user’s tapping of tabs and swiping of slides on the storefront.

You can use this to specify places in which you want to insert page builder elements
