Display optgroup label as initial option [closed]

Answer 1

You can use a standard option element and simply specify the disabled attribute:

<select>
    <option disabled="disabled" selected="selected">Select Price</option>
    <optgroup label="Gold">
        <option>5.00</option>
        <option>10.00</option>
    </optgroup>
</select>
