Conditional rules allows a user to control whether a form component will display based on the value of a previous component. Conditional rules can be added on each component (element, page, layout) or on the Submit button(s) to control whether that component will appear or not.
 
When adding a conditional rule to an element, you can control whether it will be visible, enabled/disabled or required/optional. 

When adding a conditional rule to a component you will need to know (or confirm) the key that is associated with the value you are applying the rule to. For select options, the default keys for options are numbers starting with 1 for the first option, but these keys can be changed in the select options field settings.   
 
Note: Users need the correct permissions to access the forms list and create conditionals.
