I have created a business listing web app and have allowed the users to select categories for their listing.
Now I would like the user to be able to manage the categories of the listing.
I can add the category list to the edit layout and users can select categories but it doesn't show which categories are already selected for the web app item.
If a user saves the web app without selecting all of the relevant categories or none, the web app item will only have the newly selected categories and all of the preselected categories will have been removed.
Is there a way to be able to show the categories that are already active for the web app item?
