How to change standard form in Bootstrap?

Please tell me how in standard form with a dropdown menu in Bootstrap is to replace the button-arrow on the icon without a button? In the end, I want the form look like a button with a dropdown menu, but with the functions option and select.

You should have a code thrown, so it is difficult to say. In General extend the bootstrap class, which define what this button, no arrows. Get a customized bootstrap without affecting its source code.
Thanks for the reply, but I'm new and for me it is difficult. And code like this:

UAH (Hryvnia)USD (Dollar)EUR (Euro)RUR (Ruble)
If you can tell me. - Zack89 commented on July 9th 19 at 14:06
