The drop-down with options is part of what's called ShadowDOM . In current CSS level 3 specifications, there is no way to achieve most ShadowDOM elements. You can read the specs about ShadowDOM here , though there is not much there about what you want.

But there are options like Select2 that redraws the entire combobox using Javascript.
