Expand menu for parent of active child

In case it helps anyone here, I went ahead and rolled my own based on Son of Suckerfish (until the nifty Nice Menus module can handle this at least). Feel free to borrow the code from http://www.sunrisesprings.com/

I had to assign a class to ancestors of the current active page, using the basic idea from http://drupal.org/node/87902 but with the changes to assign it to the li element rather than the a:

function phptemplate_menu_item($mid, $children = '', $leaf = TRUE) {
  $active_class = in_array($mid, _menu_get_active_trail()) ? ' active-trail' : '';
  return '<li class="'. ($leaf ? 'leaf' : ($children ? 'expanded' : 'collapsed')) . $active_class .'">'. menu_item_link($mid) . $children ."</li>\n";
}

I had to include the IE7 fix for Son of Suckerfish in the header, from http://www.builtfromsource.com/2006/10/23/a-fix-for-suckerfish-dropdowns... which was:

<!--[if IE]><style type="text/css">.content ul.menu li:hover {position: static;}</style><![endif]-->

Since Drupal's menu ul and li elements are only assigned classes, I had to make sure that my menu was contained in some unique ID element on the page (OK if there are other things in that element besides the menu), because the IE javascript code for son of suckerfish uses getelementbyid and needs and ID to latch onto and search for LI elements

Then it was a matter of balancing the code to tell son of suckerfish to act on all class=expanded li/ul combos, and then afterwards set anything with a class of active-trail to not exhibit son of suckerfish behavior (clear: both, position: relative, left: auto, display: block)

A little complicated, but it works now.

Please still keep my request in to have Nice Menus incorporate this feature - we'll promote it as far and wide as we can if it could only do this.

nlink,

You set all menus to be expanded.

Then, the son of suckerfish CSS will actually turn those into drop-down/out menus. NOTHING will actually BE expanded, but the menus need to all be set as expanded so that the nested UL UL code exists for the CSS to act upon.

Feel free to follow what I did in reply #1 and at that sunrisesprings.com website - it works!

The only bizarre thing I've noticed is that periodically, some of the menus revert back to an unexpanded state - which won't work, obviously.
