The <select> element defines a drop-down list:
Example
<label for="class">Choose your Class:</label>
<select id="class" name="class">
<option value="6th">6th</option>
<option value="7th">7th</option>
<option value="8th">8th</option>
<option value="9th">9th</option>
<option value="10th">10th</option>
<option value="11th">11th</option>
<option value="12th">12th</option>
</select>
The <option> elements defines an option that can be selected.
By default, the first item in the drop-down list is selected.
To define a pre-selected option, add the selected attribute to the option:
Example
<option value="10th" selected>10th Class</option>
