Using Pattern Trigger (Regex) in Webform Conditional Logic in Drupal 8

✅ Quick Answer: Use ^(Value1|Value2|Value3)$ in Pattern trigger to check for multiple values.

When you need to create survey style forms in Drupal 8 Webform is the clear winner. It's powerful enough to create all sorts of forms and you can even give it to your editor so they can create their own, after a little training, of course.

One part of Webform which I like is the ability to define conditional logic. For example, you can show or hide a text field based off a value from another element. You can also make an element conditionally required. It's a very useful part of Webform, and you do all of this through a UI, no custom code.

Defining simple conditional logic, check if element value has a single value, is pretty straightforward. But when you have to deal with multiple values, this is where things get tricky.
