| Location | Form Rules |
The Show Control step selectively shows a specific Form Control. Developers can dynamically control the visibility of a control based on specific conditions. This step proves particularly useful when there is a need to reveal a hidden control to users based on their interactions, Flow progress, or other business rules. Pair this step with the Hide Control step to hide and show controls based on the same criteria.
