Then I assign this collection to both a gallery and a dropdown so they have exactly the same values.
As default to the dropdown I set:
So, whatever item I select I click in the gallery, it should show in the text box from the dropdown, which it does except when I select the blank item. Then the previous value keeps there untill I click another not-blank value. I've put the behaviour in a small gif:
When I put the current value in a label as in the gif, it works even when it's blank (then it just shows a blank). But it does not in the dropdown, and I have no clue how this comes or why it should happen to be like that. Is it a bug? Or is there a workaround? I've tried much, but as far as I discovered no clean solution.
