Setups from DHTML-Menu

It would be great if some setups could be taken over by the DHTML menu:

This would be the most important:
When a menu opens

• Keep other menus open.
• Close all other open menus on the page.
• Close other open menus in the same tree.

still other:
When a menu closes

• Remember which sub-items were expanded when it next opens.
• Close all its sub-items, too.

When a new page is loaded

• Remember which items were expanded on the last page.
• Expand only the currently active path.
