You can use page suffixes feature in template settings > Features. How it works is create a new menu item for the page you want to disable the mainbody. If you don't want this menu item to be visible in main menu then simply create a new menu then create new items inside that menu.
At the end of each menu item you will see menu item id.
In Template settings > Features > Suffixes for Pages add your menu item id and your suffix. For this example I have used suffix "hidebody".
In css/override.css add below code then enable css override option from template settings > advanced settings > css override "on".
- Code: Select all
body.hidebody #gkContent { display:none!important;}
or
- Code: Select all
body.hidebody #gkMain { display:none!important;}
See you around...
