Responsive menu breakpoints
You can override the set media queries in your custom css or less files. For the menu, you need to change at least two classes like so:

To hide the menu in a wider breakpoint (> 768)

@media (max-width: 900px){
  .navbar-toggle {
    display: none;
  }
  .navbar-collapse.collapse {
    display: block;
  }
}


To hide the menu in a smaller breakpoint (&lt; 768) you have to override everything from your breakpoint up to 768:

@media (min-width: 480px) and (max-width: 768px){
  .navbar-toggle {
    display: none;
  }
  .navbar-collapse.collapse {
    display: block;
  }
}
