An alternative to core menu management - adds scalability to the admin menu management screen, by loading subtrees via AJAX.
(Not related to megamenu & similar display modules - this is an admin-only content management utility)
When dealing with a site menu that contains thousands of links, the Drupal Menu UI admin interface becomes so unwieldy as to be impossible to use. When the drag & drop functions for tree management are running, a page can take minutes to render.
THIS MODULE attempts to replace the all-in-one global tree view with a similar interface, but sub-trees are "collapsed" below a certain level, and can be expanded as needed.
Drag & drop between expanded and collapsed menus should be supported.
Flex is a simple base theme designed for Drupal 6 — and soon for Drupal 7 — that combines the HTML5 boilerplate markup with a responsive, mobile-first layout. It modifies default templates to use HTML5 tags and includes theme functions that will shim other modules into the workflow for responsive CSS. Flex is lightweight and can be expanded to include any other CSS framework you want to use.
