Is there a way to display a single-hierarchy taxonomy terms separately? For example, if we have this list:

Parent1 --child1 --child2 Parent2 --child3 --child4 --child5

I want to show two drop-down menus, populating the first one with:

Parent1 Parent2

Once a selection is selected in this first drop-down menu, a second drop-down menu is populated with the children based on the selection of the first drop-down menu. What's the best way to do this?

There are several modules that should address this issue. I've used Content Taxonomy (http://drupal.org/project/content_taxonomy), which optionally implements Active Select (http://drupal.org/project/activeselect). There is also Hierarchical Select (http://drupal.org/project/hierarchical_select), which doesn't depend on cck the way Content Taxonomy does.
