Hide 3 dots (...) in dropdown fot cetain situations

In wy.by we have an object group dropdown and then dependent object group member dropdown. We want to have a possiblity to click for object group member details (ctrl+click on a blue text), but we don’t want to have three dots … to click into the screen with a list, since such a list is dependent on other dropdown.

So one solution is to tell in a menu binding model element not to show the dots at all.
