This should (hopefully) be an easy thing to answer. I have a collection view that is bound to a JSON data source, and a button in the first level of the JSON file that I store a value for (in Preferences) and change the button based on if it’s stored or not (color, text changes). It then creates a child collection view, which each of the items also have a button for a similar function, except that if the first button is clicked, I want to be able to hide the buttons that are for the children.
