Update 2018  You should be able to just set it using CSS like this     dropdown-menu     min-width    px      This works in both Bootstrap 3 and Bootstrap 4 0 0  demo      A no extra CSS option in Bootstrap 4 is using the sizing utils to change the width  For example  here the w-100  width 100   class is used for the dropdown menu to fill the width of it s parent        lt ul class  dropdown-menu w-100  gt         lt li gt  lt a class  nav-link  href     gt Choice1 lt  a gt  lt  li gt         lt li gt  lt a class  nav-link  href     gt Choice2 lt  a gt  lt  li gt         lt li gt  lt a class  nav-link  href     gt Choice3 lt  a gt  lt  li gt    lt  ul gt    https   www codeply com go pAqaPj59N0

You can for example just add a  col-xs-12  class to the  lt ul gt  which holds the list items    lt div class  col-md-6  data-toggle  dropdown  gt              First column              lt ul class  dropdown-menu col-xs-12  role  menu  aria-labelledby  dLabel  gt                   lt li gt Insert your menus here lt  li gt                   lt li gt Insert your menus here lt  li gt                   lt li gt Insert your menus here lt  li gt                   lt li gt Insert your menus here lt  li gt                   lt li gt Insert your menus here lt  li gt                   lt li gt Insert your menus here lt  li gt               lt  ul gt           lt  div gt    This worked ok on any screen resolution in my site  The class will match the list width to it s containing div I believe

Usually we have the need to control the width of the dropdown menu  specially that s essential when the dropdown menu holds a form  e g  login form --- then the dropdown menu and its items should be wide enough for ease of inputing username email and password   Besides  when the screen is smaller than 768px or when the window  containing the dropdown menu  is zoomed down to smaller than 768px  Bootstrap 3 responsively scales the dropdown menu to the whole width of the screen window  We need to keep this reponsive action   Hence  the following css class could do that    media  min-width  768px         dropdown-menu           width  300px  important      change the number to whatever that you need               I had used it in my web app
