Bootstrap 3 Slide in Menu / Navbar on Mobile

CssTwitter BootstrapMobileTwitter Bootstrap-3

Css Problem Overview

I am building a browser-based mobile app and I've decided to use Bootstrap 3 as the css framework for the design. Bootstrap 3 comes with a great "responsive" feature in the navigation bar where it collapses automatically if it detects a specific "break point" regarding the resolution of the browser. It works in a lot of situations.

But have you noticed lately how a lot of browser-based mobile apps have the primary navigation hidden out of the left of the screen, and when the toggle icon is pressed (toggled) in the top-right corner, the primary navigation slides out to the right about 2/3 of the way into the screen? This is an increasingly popular solution for navigating through browser-based apps on mobile devices and I think in theory it should be pretty easy to modify bootstrap css/js to accommodate this version of the navigation collapse feature.

How can these feature be implemented? It seems like it shouldn't take too much modification. I'd really like to hear your thoughts/solutions on this matter. Also, I think it would be a great long-term solution for Bootstrap to implement as a built-in feature.

Unfortunately I have not made any attempts to create this feature because while I am familiar with these technologies, I am predominantly a PHP/MySQL developer and I believe a feature as useful as this should be built by experts with insight that I don't have as a front-end developer.

This was for my own project and I'm sharing it here too.

This one had trouble after 3.2, so the one below may work better for you:

Bootstrap 3

I think what you're looking for is generally known as an "off-canvas" layout. Here is the standard off-canvas example from the official Bootstrap docs: http://getbootstrap.com/examples/offcanvas/

The "official" example uses a right-side sidebar the toggle off and on separately from the top navbar menu. I also found these off-canvas variations that slide in from the left and may be closer to what you're looking for..

Without Plugin, we can do this; bootstrap multi-level responsive menu for mobile phone with slide toggle for mobile:

$('[data-toggle="slide-collapse"]').on('click', function() {
  $navMenuCont = $($(this).data('target'));
  $navMenuCont.animate({
    'width': 'toggle'
  }, 350);
  $(".menu-overlay").fadeIn(500);
});

$(".menu-overlay").click(function(event) {
  $(".navbar-toggle").trigger("click");
  $(".menu-overlay").fadeOut(500);
});

// if ($(window).width() >= 767) {
//     $('ul.nav li.dropdown').hover(function() {
//         $(this).find('>.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
//     }, function() {
//         $(this).find('>.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
//     });

//     $('ul.nav li.dropdown-submenu').hover(function() {
//         $(this).find('>.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
//     }, function() {
//         $(this).find('>.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
//     });


//     $('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
//         event.preventDefault();
//         event.stopPropagation();
//         $(this).parent().siblings().removeClass('open');
//         $(this).parent().toggleClass('open');
//         $('b', this).toggleClass("caret caret-up");
//     });
// }

// $(window).resize(function() {
//     if( $(this).width() >= 767) {
//         $('ul.nav li.dropdown').hover(function() {
//             $(this).find('>.dropdown-menu').stop(true, true).delay(200).fadeIn(500);
//         }, function() {

//         });

  }, function() {
    $(this).find('>.dropdown-menu').stop(true, true).delay(200).fadeOut(500);
  });

  $('ul.nav li.dropdown-submenu').hover(function() {
