Images in select menus - JQM

Images in select menus - JQM

Hi, I would like add images to the select menu. Is it possible? Now I have this code

in css file

.AFG{background: url("flags/af.png")5px 50% no-repeat;} 
.ALB{background: url("flags/alb.png")5px 50% no-repeat;} 
//next classes

in html file

<label for="select-choice-0" class="select">Select:</label>
                     <select name="select-choice-0" id="select-choice-0">
                         <option value="standard" class="AFG">Afghanistan</option> 
                         <option value="rush" class="ALB">Albania</option>
//next states
                     </select>


but this code doesn't work, I can see 'classic' JQM select menus. Path, name of images are correct, I check this values in firebug. I read this help, but I would like add image to 'classic combobox'

Please, can anybody help me with them?
Regards
