How to Create: Collapsible Sidebar

Create a Collapsible Sidebar

Step 1 - Add HTML:

<div id="mySidepanel" class="sidepanel">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">×</a>
  <a href="#">About</a>
  <a href="#">Services</a>
  <a href="#">Clients</a>
  <a href="#">Contact</a>
</div>
<button class="openbtn" onclick="openNav()">☰ Toggle Sidepanel</button>
<h2>Collapsed Sidepanel</h2>
<p>Content...</p>

Step 2 - Add CSS:

/* Side panel menu */
.sidepanel {
  height: 250px; /* Specify a height */
  width: 0; /* 0 width - change this with JavaScript */
  position: fixed; /* Stay in place */
  z-index: 1; /* Stay on top */
  top: 0;
  left: 0;
  background-color: #111; /* Black*/
  overflow-x: hidden; /* Disable horizontal scrolling */
  padding-top: 60px; /* Place the content 60px from the top */
  transition: 0.5s; /* 0.5 second transition effect for the sidebar sliding */
}
/* Sidebar links */
.sidepanel a {
  padding: 8px 8px 8px 32px;
  text-decoration: none;
  font-size: 25px;
  color: #818181;
  display: block;
  transition: 0.3s;
}
/* Change the color when the mouse hovers over the navigation links */
.sidepanel a:hover {
  color: #f1f1f1;
}
/* Set the position and style of the close button (top right corner) */
.sidepanel .closebtn {
  position: absolute;
  top: 0;
  right: 25px;
  font-size: 36px;
  margin-left: 50px;
}
/* Set the style for the button used to open the sidebar */
.openbtn {
  font-size: 20px;
  cursor: pointer;
  background-color: #111;
  color: white;
  padding: 10px 15px;
  border: none;
}
.openbtn:hover {
  background-color: #444;
}

Step 3 - Add JavaScript:

/* Set the width of the sidebar to 250px (show it) */
function openNav() {
  document.getElementById("mySidepanel").style.width = "250px";
}
/* Set the width of the sidebar to 0 (hide it) */
function closeNav() {
  document.getElementById("mySidepanel").style.width = "0";
}
