You can set up your form to reveal the next section only when a portion is completed. You can do this using a visibility filter. Just add a filter for each section to only show when proceeding section is not empty.
For example, I set the ‘Team’ section of the form to only show when the ‘address’ field is not empty.
Note - we do not currently have conditional visibility for individual lines. It is not possible at the moment, to update options in the create form based on other values.
