Possible? Expanding dropdown menu view so more content is visible?

Hi guys,
I am struggling with dropdowns. When I expand them, they only show 4 items and also they're not scrollable, which is extremely annoying and not user-friendly. Is there a way to fix that?

You should consider using a JavaScript popup menu:

    This has its own issues, though. For example:

    - The list can't be scrolled with the mouse.

    - You can't jump to an item by pressing the first letter in its name.

    - The selected value is not saved anywhere, unless you copy it in your script to a separate field.

    Are you on a Mac?  If so, then there is a known bug with dropdowns on the Mac, which is that limited entries are shown. A couple of people on this forum have reported only seeing one dropdown entry.

    Yes, I'm on a Mac, but I had it tested by a friend on Windows and he saw the same.

    A drop-down should show something like 8 items in the list, and should be scrollable. Are you sure this is a drop-down field? Can you send a screenshot (preferably full-screen) of what you're seeing?

    Is it possible to modify the look & behaviour? Yes, it is a dropdown list. Unfortunately I can't share the whole document, but here's what every dropdown on the PDF looks like. Thanks for your help (again)!

    Oh and to specify: I can scroll it, but only by clicking on the arrows, not with the mouse...

    Dropdowns are scrollable.
