My site is coaching resource website with 5 levels, which are connected as membership plans. http://coaching.touchtight.com/register). Each plan is assigned up to certain menu levels. For example, level 1 is the free plan which is available to registered and non registered users. Level 2 plan should include access to level 1 and level 2. Level 3 plan include access to level 1, 2, 3. Level 4 plan include access up to level 4. Level 5 is a lifetime membership plan which have access to all levels(menus).
I need to implement access control to menu items so that only drop-down menu is visible to public, and menu items inside drop-down menu should be redirected to a registration page if the user is a non registered user. I achieved this on my level 1 menu item(Please check my site.) up to a certain extent as this visible even to non registered users. This differs from other levels as I need them only to display drop down menus to public/unregistered users. How can I achieve this?
