Popup menu closing on title

[ddyer0]

If I construct a combo box with a title component, clicking on that title closes the combo box without
any of the subitems being triggered. This is generally undesirable - the title looks like any other item
and it's an easy accidental target.

I've tried several kludgey workarounds but found no way to make the title area into neutral territory where
clicks are ignored.

What's a combo box with a title component?

create a menu with a title argument, show it as a popup combo box. The title becomes the zero'th element, which can't
be selected, but clicking still closes the menu.

The "game name" at the top is a title. It's not an item that can be clicked on, but if you do the popup closes. I've recently modified it to make it visually distinct from the rest of the menu, which helps, but I wish that I could arrange that clicking on it does not close the menu.

What's the code that creates that?
