在 Bootstrap 中创建响应式导航栏侧边栏“抽屉”？

Question

Trying to achieve something like this : https://www.muicss.com/examples/v1/example-layouts/responsive-side-menu/index.html

I've seen some examples online using other versions of bootstrap, but they all change the css too much, which makes it harder to learn bootstrap.

I was wondering if in Bootstrap 4 this can be done using tools like collapse, stacked pills, flexbox?

This is what I could achieve : https://jsfiddle.net/kL9u6esw/20/

What is missing from my Jsfiddle :

1. Not correctly responsive
2. The navbar isn't scrolling properly with the sticky class
3. The menu button isn't sticky even though I set the class.
4. A background dimmer, although not necessary for the answer, would be great

In my example I couldn't figure out how to insert a navbar, not sure if its necessary for it to be properly responsive.

Also not sure if having it as a columns is the correct way to do it, shouldn't it be off-canvas?

Html code :

<div class="container-fluid h-100">
  <div class="row h-100">
    <div class="col-5 col-md-3 collapse m-0 p-0 h-100 bg-dark" id="collapseExample">
      <ul class="nav flex-column navbar-dark sticky-top">
        <li class="nav-item">
          <a class="nav-link active" href="#">Active</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#">Disabled</a>
        </li>
      </ul>
    </div>
    <div class="col">
      <div class="row">
        <div class="col-12">
          <button class="btn sticky-top" data-toggle="collapse" href="#collapseExample" role="button">
            Menu
          </button>   
        </div>
        <div class="col-12">
          Lorem...
        </div>
      </div>
    </div>
  </div>
</div>

Answer 1

Bootstrap 5 Beta 3 (update 2021)

There is now an offical Bootstrap 5 Offcanvas Component that makes creating sidebars much easier. Of course it can still be done without using the Offcanvas component like this sidebar example for Bootstrap 5

Bootstrap 4 (original answer)

Sidebar navs can be very complex. This may be why Bootstrap doesn't have an "out-of- the-box" component. There are many considerations for Sidebars :

• Responsive - different width, visibility or orientation based on screen width?
• Multi-level - do the nav items have sub levels? How will this impact height?
• Toggleable - can the sidebar be toggled by a button or "hamburger"?
• Push vs. Overlay - is page content hidden behind or next to the sidebar?
• Left or right - is the sidebar to the left or right of page content?
• Fixed or sticky - how is the sidebar positioned on page scroll?
• Animation style - slide left/right/up/down?, collapse?

---

In this "sidebar" case... instead of using col-auto on the right column, use col . That way it will fill the width when the menu is collapsed: https://jsfiddle.net/0rhyzu7o/

<div class="container-fluid h-100">
  <div class="row h-100">
    <div class="col-5 col-md-3 collapse width m-0 p-0 h-100 bg-dark" id="collapseExample">
       ..
    </div>
    <div class="col">
      <div class="row">
        <div class="col-12">
          <button class="btn sticky-top" data-toggle="collapse" href="#collapseExample" role="button">
            Menu
          </button>   
        </div>
        <div class="col-12">
           ..
        </div>
      </div>
    </div>
  </div>
</div>

To make the animation a little smoother, you must override Bootstrap's collapsing transition which normally works on height

EDIT:

Based on the bounty request, I updated the sidebar with 2 more examples. These are closer to the example , and mostly use Bootstrap classes.

Minimal version

This version is closer to the example, and has the same slide left/right "drawer" animation.

body {
    height: 100vh;
    overflow-x: hidden;
    padding-top: 56px;
}

.vh-100 {
    min-height: 100vh;
}

.sidebar.collapse.show,
.sidebar.collapse.show + .col {
    transition: .18s ease;
    transform: translate(0,0,0);
    left: 0;
}

.sidebar.collapse,
.sidebar.collapsing,
.sidebar.collapsing + .col {
    transition: .18s ease;
    transform: translate(-25%,0,0);
    z-index: 1050;
    left: -25%;
}

Full version ( very close to the example ):

This sidebar features:

• fixed-width
• automatically closes on smaller screens , opens on wider screens
• can be toggled open/closed at any width
• responsive - becomes a fixed overlay on smaller widths

This full version does require a little more CSS, but some of it is optional...

Both the minimal and robust examples are much closer to the original example . It's easy to change color and tweak the styles. Here's another variation with the sidebar overlaying the toggle bar at the top.

Answer 2

So here's a possible solution to points 1-3.

The key to solving #1 was provided by @zimsystem: "Instead of using col-auto on the right column, use col. That way it will fill the width when the menu is collapsed."

To solve #2 , you need to get rid of h-100 in the first row and column:

<div class="container-fluid h-100">
  <div class="row *h-100*">
     <div class="col-5 col-md-3 collapse m-0 p-0 *h-100* bg-dark" id="collapseExample">
     ...
     </div>
  </div>
</div>

(this is not correct code, I marked the classes you need to delete with asterisks)

Once you do this, the menu column will stretch to the full length of the content column.

To solve #3 , you just need to move the button out of a sub column, into the main column. It was staying in place within the mini column you had assigned it to.

<div class="col">
      <button class="btn sticky-top" data-toggle="collapse" href="#collapseExample" id="" role="button">
           Menu
      </button>
      <div class="row">

     <div class="col-12">
       Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer in...
     </div>

Additionally, I added some CSS to the menu in case you end up having more links than in the example, so that they'll scroll properly if the list is too long for your screen.

.collapse .flex-column {
  max-height: 100vh;
  overflow: auto;
  flex-wrap: nowrap; /* Optional, if you don't want the links to form columns if they overflow */
}
.collapse .flex-column li { 
  width: 100%; 
}

The full code for this answer is here:

 body{ height : 100vh; overflow : scroll; } .collapse.width.show { transition: max-width .3s ease, min-width .3s ease; width: 100%; max-width: 100%; min-width: initial; } .collapse.width, .collapsing.width { max-width: 0; min-width: 0; width: 0; transition: all .2s ease; } .collapse .flex-column { max-height: 100vh; overflow: auto; flex-wrap: nowrap; /* Optional, if you don't want the links to form columns if they overflow */ } .collapse .flex-column li { width: 100%; }
