Menu items not visible

[JonnieP]

When the grey arrows to the right of the screen are clicked the sub-menu is hidden, how can I reinstate this?

[Illori]

when you click on that arrow a menu should appear on the left side of the screen, in that menu on the top should be a similar arrow to click to restore the top menu.

Selecting sidebar menus should not affect dropmenus.

[Arantor]

Selecting sidebar menu turns off the drop downs there.

Yes, I see it now.  Was looking at the main menu.
