title: Dropdown buttons / Spinner like the ones on the design specs from Google
body: <p>I'm wondering how can I do a dropdown button / menu like the ones we can see in the designs specs from Google and in the image bellow, so the list expands bellow right bellow the button. Do I need to set a custom layout for it instead of the <code>R.layout.support_simple_spinner_dropdown_item</code>?</p>
