Conditional Fields

Conditional Fields is an admin user interface with the ability to modify fields appearance and behavior on certain conditions when viewing content defined by dependencies between fields based on their states and values.

Details

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 and custom entities like build by ECK), 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. Or a boolean field, which if checked, makes another field invisible. But much more options are available.
