How to create a tree with filtered nodes from drupal taxonomy

I'm trying to create a menu tree in drupal like this:

- term 1
    node 1
    node 2
  - sub-term 1
        node 3
        node 4
  + sub-term 2
  - sub-term 3
        node 5
      - sub-sub-term 1
             node 6
+ term 2
etc.

(Sub-term 2 and term 2 are toggled closed.)

Some requirements:

  • Output this using something like JQuery Menu to get an interactive tree
  • Filter the nodes by cck type
  • Filter the nodes by cck field
  • Only have terms with nodes or other active terms in them show up
  • Mark the current node as such, and automatically open the tree to that point

Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.

Very strange taxonomy tree, subterm is child of node that attached in it. Usually parent term has subtree of children terms. I think only manually coded menu is possible here, no ready module exists for it. - Nikit
Maybe my example is misleading, but I didn't mean to imply that the sub-terms are children of the nodes, merely that the tree shows both a given terms nodes, and their sub-terms. I'll adjust the sketch slightly... - sprugman

Sounds like Taxonomy menu and the DHTML Menu module linked in the previous answer would get you pretty close. You'll need a view for your content to do the filtering. Here is an excerpt about Taxonomy menu from its project page:

Transforms your taxonomy vocabularies into menus with ease!

Features

  • Custom Menu per vocabulary
  • Uses the default taxonomy term path or custom paths
  • Integrate with Views
  • Integrate with Pathauto: use URL/path aliases
  • Does not interfere with other menu modules

I think this module will do what you want -- Taxonomy field menu.

It will build a traditional menu based on the connection between terms and nodes.

Just make your own custom menu and use the DHTML Menu module to make it expand/contract on click. Here is an excerpt from its project page:

... uses Javascript to reduce the number of page loads when using nested menus; this is particularly useful with Drupal's administration system.

Ordinarily in Drupal, in order to see the sub-items in a menu, you need to click the link of this item and wait for a full page load. After enabling DHTML Menu, clicking a menu link once will expand it to reveal its sub-items without reloading the page. A double-click on the item will load the page normally. Additionally, a cookie stores which menus are open and which are closed, so that the state of the menus remain consistent as you navigate around the site.
