Long / too many Menu items simply extend out of the screen

[RafaPolit]

Describe the bug If you configure more than X amount of items in menus, or give them very long names, they extend out of the screen.

To Reproduce Configure a lot of menu items with long names.

Expected behavior Detecting the screen width (and on screen resize), it should hide the "un-seable" items into an ellipsis button. Language selector and buttons should still be "fixed" to the right of the window and not disappear behind the ellipsis.

Make sure settings menu always renders on the top right without being pushed by the menus. quick fix.

After some attempts, it was not possible to introduce a quick fix that hides/collapses the options that go outside the allocated area, at the moment the applied solution is to set a maximum width so that, in the case of long elements, the action buttons will remain accessible. cc. @RafaPolit
