(I have no more developer information about the used NodeBB as i am not a administrator)
Exact steps to cause this issue:
Open a existent thread
Go with Tab key to 'Topic Tools' button
Cursor stucks in item 'Lock Topic', next item in sub-menu is not selected
What you expected:
I expected to reach all menu items in sub-menu with Cursor-Down key as in other buttons sub-menues
What happened instead:
Cursor stucks in first item of sub-menu and next items can not be selected
Submenu items reachable by mouse
Keyboard access is needed for accessibility
A webdev in our company said:
This is because NodeBB uses a hidden class to hide the opposite value (lock/unlock) so focus is lost when going over the hidden element.
This could be fixed by using a hidden attribute on the <li> element but the toggleClass code is in NodeBB core not the theme code.
There is a need to fix this because accessibility by keyboard is important for some disabled or without-mouse users.
