How do I can make dropdown list with styled button?

i need to make a dropdown list with styled button like this

at this picture the drop button maked by just button.by clicked on it i can't open list container.

if i use the native list button-it's look like this

so,is there any ideas,how style the list button,or how call the list drop down when i click on usual button?

You can change List type to "Listbox", resize it to full size and set invisible. When the button is clicked - make it visible.

hmmmm,that's good idea!i'll try it,thank's.
