.js file
$(document).delegate('select', 'focusin', function(){$(this).addClass('select_focus');
});$(document).delegate('select', 'focusout', function(){$(this).removeClass('select_focus');});.css file
.select_focus {filter: progid:DXImageTransform.Microsoft.dropshadow(OffX=-1, OffY=0, color='black') progid:DXImageTransform.Microsoft.dropshadow(OffX=1, OffY=0, color='black') progid:DXImageTransform.Microsoft.dropshadow(OffX=0, OffY=-1, color='black') progid:DXImageTransform.Microsoft.dropshadow(OffX=0, OffY=1, color='black');}
