Required fields Validation - either one field must not empty - Kentico Form

Today I would like to share how to implement the required field validation for 2 fields - either one field must not empty. Normally when we using Kentico Form(BizFrom, custom table, page type), we want to make the field is mandatory, so we just need to tick on the required checkbox to make it required. So come to the next scenario, we might need to make sure from 2 fields either one must have a value. Here is how to implement this validation on the Kentico Xperience CMS.
