I'm using Matrix and one of my fields needs to be a Select Dropdown, but since it apparently isn't an option in Matrix I had to install P&T Dropdown. Is there a way to let users enter their own value if they would rather not select an item from the list? I'd like to know how to do this P&T Dropdown and Select Dropdown, if possible. If not, are there any other options?
Also, I suppose not all field types are "Matrix compatible" and that's why I don't see Select Dropdown as an option for cell type. Is that right? What makes a field type Matrix compatible?
