IE7 border select

The IE7 doesn't support css property border on select elements (dropdown).
But there is a cool workaround for it. For example we want to set a red border, you can use this css:

/* IE7 workaround */
select {
   filter: progid:DXImageTransform.Microsoft.dropshadow(OffX=-1, OffY=0,color=#FF0000) progid:DXImageTransform.Microsoft.dropshadow(OffX=1, OffY=0,color=#FF0000) progid:DXImageTransform.Microsoft.dropshadow(OffX=0, OffY=-1,color=#FF0000) progid:DXImageTransform.Microsoft.dropshadow(OffX=0, OffY=1,color=#FF0000);
}
