Hierarchical Select

Used modules

Hierarchical Select (and its dependencies)
Taxonomy (part of Drupal core)

Demo

Want to know what the configuration looks like? I've got a short screencast for version 2. Compare that with the extremely spartan configuration in version 1!

Graceful degradation is there too: it simply reverts to the "old style" hierarchical selects -- which are simply normal selects with dashes prepended to the term names to point out the level in the hierarchy.

Original Hierarchical Select 1 demo

Titles and "required" marks are kept intact, as well as descriptions: *

Optional vocabularies are supported and they can have any hierarchical depth, even within the same vocabulary:

Selecting a location can now be done very easily, by simply creating the correct vocabulary:

New in Hierarchical Select 2: enforce_deepest and level labels

enforce_deepest = TRUE, forces you to select from the deepest level:

enforce_deepest = FALSE, allows you to select from any level:

level_labels = array('<Country>', '<City>'), enforce_deepest = TRUE, will only show the first level label:

level_labels = array('<Country>', '<City>'), enforce_deepest = FALSE, will show all level labels:

New in Hierarchical Select 2: multiple select & related features

Multiple select is now supported: *

Multiple select also supports save_lineage:

A custom dropbox title can be set:

When multiple select is enabled, you can also enable a "<all>" option:

A limit for the dropbox can be configured:
