The Profile Conditionals extension allows site administrators to configure in-page changes to fields and page elements in response to user actions.
Based on user selection, this extension can conditionally:
- Show or hide field elements
- Add (or relocate) page elements before or after other elements
- Set field values (text input, radio, checkbox, select, etc.)
- Make fields required/optional
- Select/unselect price field options
