Make sure "bootstrap-select.css" is loaded correctly.

It has .bootstrap-select > select style that is applied to style element which will hide the normal dropdown list.

Inspect the select and take a look above style is applied there? I have used above code and it is working fine when "bootstrap-select.css" is loaded.
