You can place multiple resources on a single widget.
In this case, the customer will see a Catalog with the list of resources to choose from.
If there are too many resources, you can group them by folders — resource groups.
To create a resource group, go to Resources and Widgets and do the following:
1. Click Create group.
2. Enter a name.
3. Click Add resource to add a resource to a group.
4. Click Add subgroup to add a nested group to a group.
5. Save it.
To create the catalog in the widget, open its settings and go to the Content panel.
Add resources and nested groups in the same way.
Look at the example of the catalog.
Here you can find groups with the Open button, and resources with the Book button:
