Master Select Widget is an Archetypes widget which looks and feels like a normal select dropdown; however, any time an item is selected it triggers javascript events which control the behavior of other fields in the schema. It can hide other fields using CSS, disable other widgets, and alter the vocabulary of other fields using XMLHttpRequest calls to a methods that produce AT DisplayLists (the subordinate fields must use Select, MultiSelect, or MasterSelect widgets).

You may have many of these master widgets on a page and each can control multiple slave fields. The slave fields themselves can use master widgets controlling their own slaves. Currently a master can only control one aspect (vocabulary, visibility. etc.) for each of its slaves, but multiple masters can control the same slave.
