Bulk Select

Bulk Select provides both a Form API Element and a Field API Widget with nested checkboxes. If you need a select element with the following features...

• Multiple select
• Hierarchical structure
• Only lowest-level elements selected
• Collapsible hierarchy to save space
• Quick, intuitive interface
• Graceful degradation when JavaScript is not available

...then this might be the module for you.

Included in this package is a demo module which is an example of how to:

1. Use the "bulk_select" form element in your own forms.
2. Use the "bulk_select" widget for a list field on an entity (e.g. user, node, etc)
