Simple trigger/tickbox in the status of the flow that allows a Section to be displayed collapsed or open depending on the state/transition.
State 1 - collapsed
State 2 - open
State 3 - collapsed
Thank you for submitting your idea. We believe that this already exists by using form scripts with triggers based on the status, which allows you to expand/collapse the section based on where the form is in the workflow.
There is a "start collapsed" option available.
