Multiple jQuery UI date pickers with different styling

Question

I have two jQuery date pickers on my page:

• A regular one
• A "special" one that can only pick years/months.

The special one uses some custom CSS (from here) to hide the calendar part, so only the month/years show up.

.ui-datepicker-calendar {
    display : none ;
}

However, since there is only one dialog instance on the page, the calendar is hidden for both pickers.

Is there a way to only apply this style to one of the instances? I've checked the docs to see if I could add a custom class to the dialog, but I couldn't find it.
