Forums collapse the menu

Hi

The menu has worked really well, right up to the point where I added our forums to it.
The menu structure has a ‘Page’ labelled forums under which all of the forums sit.
A couple of the forums are generic discussion areas for departments with separate teams working in the same discipline. I put the team forums into the menu as sub items of the generic forums.

The problem is that I can not get to the sub forums because as soon as I select a menu item that is a forum the menu collapses.
I have, at the moment, sort of worked around it by creating a page to group the general & sub forums under, but although this enables me to get to the sub-item forums, the menu still collapses as soon as a forum is chosen.

This is not ideal behaviour and is contrary to the way the rest of the expandible/collapsible menu works.

I have uncommented that line in the script.js file, but it has had no effect unfortunately.

Is this something you can fix please?

Many thanks, and great work!
