title: Html Form Multiple Selectbox using SumoSelect, mark required fields
body: <p>I am using <a href="https://hemantnegi.github.io/jquery.sumoselect/" rel="nofollow noreferrer">SumoSelect</a>, a jquery Dropdown, for <code>&lt;select&gt;</code> fields in my html form. How can I mark them as required when submitting the form? Native <code>&lt;select&gt;</code> fields get a notice by chrome, Firefox, etc. can I replicate that behavior?</p>
