I have 3 content type
2 menu block
In my main menu have 2 menu links (HOME | HTML)
HTML4 (menu block) show the contents of HTML4 (content type).
I configured the HTML4 and HTML5 (2 menu block) should be appear when user click the HTML (main menu). It is fine.
My question is : how to active(highlighting) HTML(main menu) when the user click a link from the HTML4 or HTML5 (2 menu block) ?
Solution : I found the module name is "menu position" http://drupal.org/project/menu_position.
This module make relationship between the main menu and content type.
Well to do that:
1> make sure you are using your own theme.
2> Write the css for the menu to highlight when one clicks inside.
jQuery to check for the children being clicked and add the highlight class to the menu name using $('#MenuDiv').addClass('highlightClass');
If you post code of your menu, maybe I can help from jQuery point of view.
