Automated closing of the dropdown menu

[ambassador000]

As visible on screenshot below, default setting is "All". When clicking on an arrow right to the "All" text, dropdown menu is opening. By clicking again on arrow, dropdown menu is closing. By clicking on "All", dropdown menu is opening, but by clicking on "All" again, dropdown menu is reopening again, while it would make more sense to close (to have the same function as arrow) while leaving the "All" selected or whatever was already selected.
