I assume this will need to be performed by not using the time component, but rather, by using 2 separate dropdowns: [HOUR][MINUTE]. I would like these fields to have the following values, for example:</p> <p>[HOUR]= 4,5,6,7<br /> [MINUTE]= 00, 15, 30, 45</p> <p>As you can see, that gives the user 16 options. As an option is selected/submitted upon, I would either like to "grey out" that option or remove it from the dropdown. Think of this as a reservation type form where only 1 person can pick 1 time.</p> <p>Does anyone have a good method of performing this?</p> <p>Thanks,<br /> Travis </p>
