I have 2 collections, one with one item and many fields, and the other with one field but 11 items.
I was trying to connect my dropdown button to the 11 item list, but for some reason it is 'greyed out' when I preview the site.
When I tried to connect it to the one item list then it was ok.
The 11 item collection has one field and sorted according to 'Date created'.
Any idea why this happens?
