I tried to highlight the first option of the selection window, but it only works in Firefox, and not in other browsers (Chrome, IE). Here is the code I tried.
HTML
<select id="htmldisabled"> <option class="bold">test1</option> <option>test2</option> <option>test3</option> <option>test4</option> <option>test5</option> <option>test6</option> </select>
CSS
.bold { font-weight:bold; }
See the demo in jsfiddle .
