multicombo popup close button

Hi there guys!
Is it possible to have a close button next to “Select all” in multicombo popup (check image attached)? screenshot.png - Google Drive
I was trying to reuse this example somehow but with no success:

Hey there intregal!
Thanks for your respond.
I can’t see any close buttons in your example.

Now I see what you meant. “Select” button can server same purpose as “Close” button. One just need to change the text.
Many thanks!
