Free tagging

This allows terms to be typed into a field, rather than be presented as a pick list of fixed terms. It is useful for adding terms 'on-the-fly'. It is very useful if you have chosen Disabled for your hierarchy. The Tagadelic module requires a vocabulary set up like this.

Multiple select

This allows you to allocate content to more than one term by using Ctrl-Click. For example you might have an item on Brie cheese that you want to allocate to the terms Soft Cheeses and France.

Required

This forces the author to allocate content to one or more of the vocabulary terms.
