Conditions Generator will help you write your own conditions for Conditional Fields and Conditional Validation for Elementor Pro Form in just a few clicks. 

Notice: Select, checkbox and other fields can have both a label and a value separated by a “|” character. When possible we recommend taking advantage of this and to use values that are only composed of letters from the english alphabet, underscores, and numbers without spaces.

Also notice that the conditions of a field should only be based on fields that precede it in the form.
