How to copy this little button next to the <select> element?

Question

I want to change the style (background, etc.) of a small button with an arrow, which is located on the left side of <select>. Does anyone know if this is possible and how to do it?

Answer 1

I don’t know of any good cross-browser methods for select box style using only CSS, but in the past I was successful with jquery ui
