Feature Request - New Condition on Drop Down Menus

I have an issue with two drop down menus spaced close to each other.

It would be good to allow a condition that disables one dropdown when another dropdown is dropped down… because what happens is the user attempts to select an item from the drop-down list but instead of selecting the item, it selects the drop down BELOW it and focuses the input…

Unless there is another way to go about this, it’s quite bad UX.
