I am using Bootstrap Mega Menu Module to create multicolumn sub menus under main menu. My menu tree is like:
Home (Single article, default) Fields of Study (Article Category List: show articles in a category named FoS) - History (Single article: under FoS) - Literature (Single article FoS) - Social researches (Single article FoS) ...
If I use Joomla's built-in menu module, I can see sub menu items when I click on "Fields of Study" item. There is no postback.
If I use Bootstrap Mega Menu Module, the page opens the category list page when I click on "Fields of Study" item. eventhough I can see the submenu opens, I cannot click on the items in it, because the page reloads.
