form_dropdown -> optgroup validation issue

[eluser]Evil Wizard[/eluser]
The html validation error is because the <optgroup> tag is expecting to contain child elements, that is why it is unfinished, either contain the list within the optgroup or omit it.

Code:

<div class="formrow">
    <label for="program">Program: </label>
    <select name="program">
        <option value="113">aaaaaa</option>
        <option value="114">bbbbbb</option>
        <option value="116" selected="selected">ccccc</option>
        <option value="115">ccccc</option>
    </select>
</div>

or

Code:

<div class="formrow">
    <label for="program">Program: </label>
    <select name="program">
        <optgroup label="0">
            <option value="113">aaaaaa</option>
            <option value="114">bbbbbb</option>
            <option value="116" selected="selected">ccccc</option>
            <option value="115">ccccc</option>
        </optgroup>
    </select>
</div>
