Question
I found that an old code has been submitting illegal values into DB from time to time. I have a select with many options and between options there are some "Headings" that I have disabled.
MYSQL field for errorcode is varchar(2). I have found some "SU" values from that field. That means that the first option, that is disabled, gets submitted.
I looked at the page with IE, Firefox and Chrome and in all of the browsers the first option was disabled and i couldn't select it. I don't have an idea how to debug it.
How to solve this?

Solution
Try to convert your code to something like:
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
More info: w3schools optgroup
It's better way to set headings.
