Hi i think you can do it using CSS like this you can change breakpoint bootstrap menu
@media (max-width: 1200px) {
.navbar-header {
float: none;
}
.navbar-left,.navbar-right {
float: none !important;
}
.navbar-toggle {
display: block;
}
.navbar-collapse.collapse {
display: none!important;
}
.navbar-nav {
float: none!important;
}
.navbar-nav>li {
float: none;
}
.collapse.in{
display:block !important;
}
.navbar-nav .open .dropdown-menu {
position: static;
float: none;
width: auto;
margin-top: 0;
background-color: transparent;
border: 0;
-webkit-box-shadow: none;
box-shadow: none;
}
}
