The attached screenshot shows how the category dropdown appears on my mobile device (Google/LG Nexus 4). It doesn't have the same styling that it does on the desktop version of the site (and so, in my opinion, it doesn't match the textbox next to it, which does retain the same styling as it has on the desktop version of the site). How can I make it so the dropdown is styled like it is on the desktop version of the site?
This screenshot is from an Android device. I think some iPhone browsers will exhibit similar behavior to this Android device (i.e. using their built-in styles for the dropdown).
