There are many menu's within KDE that allow multiple selections, yet close after the first selection (click). E.g. right-click on a window's title bar > activities or in dolphin's menu the additional information etc.

Closing the menu on the first selection (click) adds multiple mouse clicks, i.e. if one has five activities and wants to have a window on three of them one has to click and move the mouse _nine_ times.

If the menu would not close after the first selection on a checkbox there would only be five clicks and a lot less needed mouse movement.

There might even be menus that have radio+checkbox lists and could be left open, e.g. dolphin's view > sort by.

If one selects the criterion to sort by the menu is closed although one could still pick "descending" and "folders first" (two checkbox items).

So IMHO it would be useful that all menus that allow multiple selection, i.e. with checkboxes, do not close when one selects an item but only when clicking outside them.

Reproducible: Always

Steps to Reproduce:
- Open a menu with checkboxes, i.e. multiple items can be selected and enabled
- Select all of them

Actual Results:  
The menu closes after each item the user has selected

Expected Results:  
Do not close when selecting as multiple selections are possible within that menu.
