Before designing your store pages, you can choose which widgets and/or stacks are visible and which are hidden from view. Layouts have access to a set of widgets and stacks displayed within a component library. Within the Code tab you can choose to hide any of the widget and stack library components from view.
Note: Choosing to hide components already in use has no impact on those particular widget and stack instances.
To configure your component library:
Open the Design tab and click Code.
Scroll down to view the Advanced options and click the Component Selection menu to display the Component Selection page.
Select the widgets/stacks you wish to hide. Once selected, these changes are automatically saved.
