Hi,
Firstly you need create menu item and sub-menu items. I assume that menu is Top Nenu
Secondly, go to Module manager and choose module Top Menu to edit (if it have not existed yet, please create it via New button). Notice to:
- Put the module to position top-nav
- Choose Always show sub menu item (at parameters area at right side)
- min and max level, put 0
Then save the change.
And please make sure you did not installed any 3rd party extension which use other than mootools js libraries make conflict.
Thanks for using our products!
