[Dropdown] Dropdown menu item should open upwards if there is not enough room on the screen

[bdaunton]

The auto upward/downward open is not working correctly with the vertical menu item variation.

The issue is present in the documentation and is displayed by all of the dropdown items on the page.

Im probably being pretty dull, but can you elaborate on how to reproduce? Does this require a menu with enough items to cause it to be off screen to the bottom but not the top?

[bdaunton]

Yeah.

So right now on the doc page, the dropdown menu items are going off screen.

Instead of opening upward.

This became an issue for me when using a dropdown item in a right click context vertical menu.
