100$ - Taxonomy Tree AJAX upload

the ajax load of child terms can be activated but introduces two big problems:

1. doesn't work for people who have deactivated JS
2. default value / saved value: if a child term gets selected and the node gets updated it can't get selected by default because the branch isn't loaded (this part would be much work to implement)

sorry, no time for this. but would be a nice feature!

I had the same problem (with over 4000 terms) so I've written some code that loads taxonomy term tree branches on node/edit pages as branches get selected. It works similarly to taxonomy tree however it only loads the terms that are required and not the entire term tree (on node/edit it loads the top level terms (parent = 0) + tree of the term(s) that is selected).
Patch to follow.

Extract the file attached into your content_taxonomy module folder. Then download Term Tree from http://drupal.org/node/369821 and put it in your modules folder. Once you've enabled these modules you'll have an additional widget - at the moment it will only work for radio buttons (eg only 1 value in number of values dropdown).

Have same problem too.
The solution I can think of is a field that combines tree and autocomplete. autocomplete holds all the selected terms while tree is only used to show terms. And when a term is selected, javascript will populate the term to the autocomplete field.
Haven't had time to implement it...

@All: If you need a hierarchical display that reflect the taxonomy the multiselect module doesn't do that.
http://drupal.org/node/446052

you can css it to be hierarchical. Need some php work though.

Best module atm to work with large vocabs is Hierarchical Select. Try it out, there's working patch I posted in HS issue queue. See #342992: Port HS support for Content Taxonomy to Drupal 6

thanks nonsie

@all: The latest term_tree dev version can be found at http://drupal.org/node/369189/release

Please reopen issue if problem still exists.
