    Example #2

    The example below is invalid, as the first child element got an empty value attribute. In line 5, I have mentioned .

    Code:

    <form action="#" method="post">
<div>
<label for="Country">Country name</label>
<select required aria-required="true" id="Country" name="Country">
<option>Choose</option>
<option value=" CN"> Canada</option>
<option value="DM">Denmark</option>
<option value="ETH">Ethiopia</option>
<option value="NZ">New Zealand</option>
<option value="sa">Spain</option>
<option value="IND">India</option>
<option value="SL">Sri lanka</option>
<option value="It">Italy</option>
</select>
</div>
</form>

    Output:

    Conclusion

    It helps define the input field’s state and seeks the browser to validate the client-side input field. Being a fantastic element in HTML5 makes client-side form validation easy and provides better user enhancements. Their instant methods with just one piece of validation improve user – interaction.
