HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as option.
Drop-down lists can be defined in HTML by using the <select> tag, containing the different <option>s. Each <option> must have a name, which can be either contained between <option> and </option>, or alternatively using the label attribute.
Example:
<select name="size">
<option value="s">small</option>
<option value="m" label="medium"></option>
</select>
<select> elements that are required and are not multiple need a placeholder option that has no value, for example:
<select required>
<option value="">choose size</option>
<option value="s">small</option>
<option value="l">large</option>
</select>
The <option> element no longer accepts a name attribute, which is now obsolete.
Example:
<select id="pet-select">
<option value="">--Please choose an option--</option>
<option value="dog">Dog</option>
<option value="cat">Cat</option>
<option value="hamster">Hamster</option>
</select>
