I want stop the form submission if the default disabled option is selected.

i tried required attribute on all of the child elements.

here is my Code:

<div class="form-group form-check">
    <label>who you are?</label>
    <select class="form-control" name="usertype" required>
       <option disabled selected>Select user Type</option>
       <option value="user">user</option>
       <option value="admin">admin</option>
    </select>
</div>

I want to submit the form if the user select one of the two option not third one.

is there any HTML trick/Attribute to tackle this problem, or some Jquery please?

Thank you in advance
