 # Conditional Fields
 
-Conditional Fields allows you to manage sets of dependencies between fields. When a field is “dependent”, it will only be available for editing and displayed if the state of the “dependee” field matches the right condition.
-When editing a node (or any other entity type that supports fields, like users and categories), the dependent fields are dynamically modified with the States API.
-A simple use case would be defining a custom “Article teaser" field that is shown only if a "Has teaser" checkbox is checked, but much more complex options are available.
