In the new UI, how do you display a CMS collection in a dropdown menu?
My CMS has sub-categories.
No different from the prev UI.
You drop a collection list in and then put a dropdown item inside the collection list and bind everything up.
If you’re trying to create some form of multilevel dropdown list, you’ve got a lot more complexity in what you’re trying to do. Most likely you’ll need to use custom code or interactions to build it.
