Hi, 

The first filed in my form is a dropdown and when users select a specific option, I would like the other fileds to be autoatically filled in based on the selection for the dropdown. 

E.g. booking form has select filed for 'type of booking' with options: runner, studio, other. Other fields include, 'booking title', booking description. 

If user selects type of booking as runner - then, project title should be set to 'Runner required'. 

If user selects type of booking as studio - then, project title should be set to 'studio job' ect. 

How can I achieve this?
