I have a form on a page with inputs. Some are kendo dropdownlists, some are basic html inputs, etc. That form uses a kendo validator. Normally when I want a field to be required I just add the required attribute to the input or select. That is what I'm doing here. Where the question arises is that as the user is doing other things on the page some of the fields in my form become not required or required again. How do I dynamically change the required state of a field in a kendo form after the form controls and validator have been initialized? Can I simply remove the required attribute from the basic html form element or must I do something more?
