I have two Dropdown selectors in a form. Both need to allow users to select multiple options, but NEVER allow ALL options to be selected. At the top of the lists is a "Select All" options checkbox. I don't see any way to remove it in the form setup. I would expect it to be an optional feature that I could toggle on if I wanted it. I do not want it.
Is there any way to mitigate this issue? The people who use the form do not read the instructions, so just including a "Do not 'Select All'" instruction will not be the solution.
