For non-admin users while adding content on the homepage or add widgets list on the dashboard does not show a few options, for example, Interactive Filters is missing from the drop-down here.
The widget categories are fetched from the sys_widgets table. When the dashboard loads, categories are filter based on the role permissions of the user. Most probable cause if a few options are missing from this list is likely because the user does not have enough permissions.
As admin role user you can take the following steps to correct the issue:
1 Go to <INSTANCE_URL>/sys_widgets_list.do
2. Click to open the widget users are not able to view
3. Review the roles available on the record. Edit and add/remove the roles as needed. If no roles are added the option is available to all users.
