A template based on t3 boostrap framework has a problem when click a menu item where there is a submenu dropping down. The visitor has no possibility to click the submenu item. The problem occurs in the android native browser but works fine in chrome for android. Some reports says the same problem occurs in the iphone/Ipad safari browser too.
To resolve this, go to the templetes in joomla backend and configure the t3 bs. Go to navigation and change dropdown trigger from hover to click (as tablets and phones doesn’t have the possibility of hovering).
