Given the importance of using landing pages in relation to marketing, please consider creating a feature built into your templates that have top menus where one could unpublish the top menu somehow on certain content pages, i.e., landing pages that payoff marketing campaigns. It is a recommended "best practice" to not have any menus or other navigation on landing pages to distract from the core action directed at the visitor.
I know that if the menu was a module, one could unpublish it from that page, but in AppSite, and probably other templates Gavick makes, the mainmenu module is already unpublished by default as is the topmenu module, yet the menu in the template always displays across the top.
If there is already a solution that would work for disabling the mainmenu on landing pages, please let me know.
Thanks,
