Menu
To create a collapsible navigation bar, use a button with class="navbar-toggler", data-toggle="collapse" and data-target="#thetarget" . Then wrap the navbar content (links, etc) inside a div element with class="collapse navbar-collapse" , followed by an id that matches the data-target of the button: "thetarget".
A "navbar" is an area on a page that contains navigation components (links, buttons, etc) for getting to other pages of the website. A "nav" is an HTML element that is normally used to enclose other elements related to navigation.
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:
CSS
/* adjust body when menu is open */
body.slide-active {
overflow-x: hidden
}
/*first child of #page-content so it doesn't shift around*/
.no-margin-top {
margin-top: 0px!important
}
/*wrap the entire page content but not nav inside this div if not a fixed top, don't add any top padding */
#page-content {
position: relative;
padding-top: 70px;
left: 0;
}
#page-content.slide-active {
padding-top: 0
}
/* put toggle bars on the left :: not using button */
#slide-nav .navbar-toggle {
cursor: pointer;
position: relative;
line-height: 0;
float: left;
margin: 0;
width: 30px;
height: 40px;
padding: 10px 0 0 0;
border: 0;
background: transparent;
}
/* icon bar prettyup - optional */
#slide-nav .navbar-toggle > .icon-bar {
width: 100%;
display: block;
height: 3px;
margin: 5px 0 0 0;
}
#slide-nav .navbar-toggle.slide-active .icon-bar {
background: orange
}
.navbar-header {
position: relative
}
/* un fix the navbar when active so that all the menu items are accessible */
.navbar.navbar-fixed-top.slide-active {
position: relative
}
/* screw writing importants and shit, just stick it in max width since these classes are not shared between sizes */
@media (max-width:767px) {
#slide-nav .container {
margin: 0;
padding: 0!important;
}
#slide-nav .navbar-header {
margin: 0 auto;
padding: 0 15px;

#slide-nav.navbar-inverse #slidemenu {

/* this is behind the navigation but the navigation is not inside it so that the navigation is accessible and scrolls*/
#slide-nav #navbar-height-col {

/*fast clearfixer*/
}
#slide-nav .navbar-form .form-control {

Bootstrap 5 Beta 3 (update 2021)
Introducing the new Bootstrap 5 Offcanvas Component
Bootstrap 4
Create a responsive navbar sidebar "drawer" in Bootstrap 4?
Bootstrap horizontal menu collapse to sidemenu
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..
