Since Bootstrap 4 nor Bootstrap 3 don't provide one, we will build 5 separate solutions, each of them with slightly different features. Originally, I published this tutorial for Bootstrap 3 in 2017. Now, in 2018, I upgraded it to Bootstrap 4 and made some improvements based on your feedback. The Bootstrap 3 version is a part of the download too, in case you would need it, though. Basic files Before we dig into coding, we should first set up our starting template with all the necessary files. Also, I include Font Awesome 5 to be used on the buttons and menu items in one example. In this case, we'll give. By doing this, the sidebar will take the height of the page content. As the content increases, sidebar height dynamically increases. Sidebar menu and its content Now, let's fill our sidebar with some content. I'll place there a sidebar navigation menu that will contain some demo navigation links and bootstrap 4 side menu some Bootstrap 4 drop-down menus. Note, that we also added an. In this case, I used homeSubmenu for this approach. Pages Page 1 Page 2 Page 3 Be sure to add aria-expanded to the dropdown's control element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If you've set the collapsible element to be open by default using an. Sidebar toggle button Now it's time to add the sidebar toggle button. This button will handle opening and closing of the sidebar. We will place it outside the sidebar itself. It doesn't matter where it is located in your content as long as it's outside the sidebar, i. Let's place it into the Bootstrap navbar in the content div. The most important thing for this approach is to use the flex property for the. As I mentioned above, stretch value will equalize both page content and sidebar height. As a result of using flexbox properties, page content content will take the remaining width of. This behaviour will be applied when the sidebar has an. Sorry I did not come up with some better class name when I wrote this tutorial in 2017. It will have an opposite behaviour on mobiles where sidebar. We'll use this class later on in the JavaScript part, too. This means bootstrap 4 side menu the initial height of the sidebar will be at least equal to the screen height. Also, its height will bootstrap 4 side menu when the page content would increase. We are using standard Bootstrap 4 class. This class adds a small triangle next to the drop-down links. Instead of appearing bootstrap 4 side menu default, it'll be hidden and appear only after clicking the toggle button. Like this, we will save valuable space for your content and show the navigation to the user only when needed. Basically, what we need to do here is to reverse the. To give it a more fancy look, I have styled it a bit more. It is all included in the download package, so I will just quickly mention it here without any further comments. By default, the sidebar will appear, i. After clicking the toggle button, the sidebar will be given an. The page content will take the full-screen width too. Re-clicking the toggle button will remove the. Fixed positioned scrollable sidebar In this part, we'll make a similar sidebar but it will be fixed. This means that it won't scroll along with the page but it will stay fixed at the same place. This will apply only to larger devices with the width of 768px+. However the content extends, the sidebar still will take entire viewport height. For this, we'll replace min-height: 100vh with height: 100vh. We'll add two extra tricks in the JavaScript, let's have a look at them now. JavaScript The first trick is that I'll replace the default browser scrollbar in the side menu with a custom one. We will need the scrollbar there just in case navbar would be too high to fit in the viewport. For this purpose, I'll use. The reason for this is to keep things consistent and to open a navbar with closed dropdowns every time. If it has one, it's open, if not, it's closed. We told our JavaScript that if this class is present, please remove it. Also, please change the aria-expanded value from true to false so the arrow will return to its logical direction. This makes our fixed sidebar navigation complete. Let's have a look at what we've built. Fixed scrollable sidebar menu with a content overlay In this approach, we'll make a side navbar similar to the one that Google uses for their navbars on tablets and mobile phones in. The sidebar will cover the left part of the page content when it's open and the rest of the content will be covered by a dark transparent overlay. This button will be responsible for the closing of the sidebar when it's open. And since we'll apply a transparent overlay, let's insert an. By default, the sidebar will be hidden. When the toggle button is clicked, both. Bootstrap 4 side menu imagine it as layers, the page content will be the back layer. The overlay will cover the content of the page to allow user's eye easily focus on the sidebar itself. Finally, the sidebar will be the front layer. To achieve this layering behaviour, we will simply use z-index property. As mentioned before, we will be also adding a dismiss button to the sidebar. It will be positioned absolutely at its top right part. Here, we already have a close button inserted in our sidebar, so the toggle button function is only to open the sidebar. To clarify the mechanism, by clicking the toggle button both overlay and sidebar appear, and by clicking the sidebar close button, both overlay and sidebar disappear. Time to check the demo. Partially collapsing static sidebar In this example, we will, instead of building a sidebar that collapses entirely, build a Partially collapsing side navbar. The side menu will convert itself into a compressed version after the toggle button click. Let's use the first approach's markup as a starting point. We will use for the icons in the side menu. The styles of the compressed version will be added to the class. For example, we will downsize the font size of the anchors' text, align it to centre and make it render below the icon. Also, we will move the arrow to the very bottom of every anchor, or adjust the padding around the dropdown links. To achieve this, we can only copy the styles from. We should have a nicely working partially collapsing sidebar. Let's have a look at the results. Further Improvements There is always room for some further improvements and tweaks. As a bonus, I would like to show you how to prepare an animated hamburger menu icon for the toggle button, and also how to add eye-catching animation for the opening and closing of the sidebar panel. But instead of using a Glyphicon for the toggle button, let's place three spans there instead. There'll be three bars under each other and we'll give them a fancy transition with a cubic-bezier transition. I often use this to produce cool transitions, you can choose from some pre-build transitions or make your custom one easily. When bootstrap 4 side menu off the canvas, the bars will be parallel to each other. By default, the sidebar will be open, so the initial state of the bars should be crossed. We'll use transform property to achieve that. The first bar will be rotated by 45 degrees, the last bar will be rotated by 45 degrees in the opposite direction. The second bar will be hidden in this moment. To make that, we will use jQuery to toggle. This class cancels the rotation of the bars and makes them all visible. We'll make a door-opening animation when the user closes or opens the sidebar. First of all, we should add perspective property to the container. Our container in this case is. The perspective property defines how many pixels a 3D element is placed from the view and allows you to change the perspective on how 3D elements are viewed. Then, we'll rotate the sidebar vertically by 100 degrees during collapsing out using transform property. The transform-origin property allows you to change the position of transformed elements. Here we'll rotate the sidebar from the center left side. The default state of the hamburger menu should be returned to the parallel state.
