Adding rules to forms allow you to show and hide form components based on other form inputs.
Example 1
Show a section if checkbox is selected
Example 2
To show an input based on a specific value. In this case a 1 star rating
Example 3
You can use rules to show/hide based on Regular Expressions (Regex) to check if an input matches. e.g. the | is OR so matches Jacket|Deli will be for Jacket or Deli.
Example 4
A Custom String can allow you to concatenate multiple inputs, use { } with Column Names.
