What is a visibility formula?
Visibility Formulas are small formulas that interact with Custom Fields. They are used within your site to make fields appear when specific options have been selected from another field. For example, let's say you have a custom field asking if the requestor needs chairs. We can use a visibility formula to have a new field appear asking how many chairs if they select yes. In this article, I'll demonstrate a few common visibility formulas and how to use them.
Making a field appear if a checkbox is selected
Formula: {Source Field}
Making a field appear based on a dropdown list selection
Formula: {Source Field} == "Dropdown Selection"
Making a field appear if multiple indicated options are selected from a dropdown
Formula: includes({Source Field}, “Option 1”) || includes({Source Field}, “Option 2") repeat as needed
