Thank you! This solved my problems with our complex menu! :)

Thank you! this is great for using with the LMS theme, this has been an issue for a while conflicting with this theme!

Thank you so much for this! :)
...and for anyone who's not sure how to use this plugin (like me!) ...if you download to your computer using the top-right 'Download Zip' button on this page, then change the name of the zip file to something like 'Nav Menu Rules Toggle' ...and just upload it to your plugins page like you usually do. :)
