Filter Dropdown

Try it Yourself »

Create a Clickable Dropdown

Create a dropdown menu that appears when the user clicks on a button.

Step 1) Add HTML:


<div class="dropdown">
  <button onclick="myFunction()" class="dropbtn">Dropdown</button>
  <div id="myDropdown" class="dropdown-content">
    <input type="text" placeholder="Search.." id="myInput" onkeyup="filterFunction()">
    <a href="#about">About</a>
    <a href="#base">Base</a>
    <a href="#blog">Blog</a>
    <a href="#contact">Contact</a>
    <a href="#custom">Custom</a>
    <a href="#support">Support</a>
    <a href="#tools">Tools</a>

Example Explained

Use any element to open the dropdown menu, e.g. a <button>, <a> or <p> element.

Use a container element (like <div>) to create the dropdown menu and add the dropdown links inside it.

Wrap a <div> element around the button and the <div> to position the dropdown menu correctly with CSS.

Step 2) Add CSS:


/* Dropdown Button */
.dropbtn {
    background-color: #4CAF50;
    color: white;
    padding: 16px;
    font-size: 16px;
    border: none;
    cursor: pointer;

/* Dropdown button on hover & focus */
.dropbtn:hover, .dropbtn:focus {
    background-color: #3e8e41;

/* The search field */
#myInput {
  border-box: box-sizing;
  background-image: url('searchicon.png');
  background-position: 14px 12px;
  background-repeat: no-repeat;
  font-size: 16px;
  padding: 14px 20px 12px 45px;
  border: none;
  border-bottom: 1px solid #ddd;

/* The search field when it gets focus/clicked on */
#myInput:focus {outline: 3px solid #ddd;}

/* The container <div> - needed to position the dropdown content */
.dropdown {
    position: relative;
    display: inline-block;

/* Dropdown Content (Hidden by Default) */
.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f6f6f6;
    min-width: 230px;
    border: 1px solid #ddd;
    z-index: 1;

/* Links inside the dropdown */
.dropdown-content a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;

/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #f1f1f1}

/* Show the dropdown menu (use JS to add this class to the .dropdown-content container when the user clicks on the dropdown button) */
.show {display:block;}

Example Explained

We have styled the dropdown button with a background-color, padding, hover effect, etc.

The .dropdown class uses position:relative, which is needed when we want the dropdown content to be placed right below the dropdown button (using position:absolute).

The .dropdown-content class holds the actual dropdown menu. It is hidden by default, and will be displayed on hover (see below). Note the min-width is set to 230px. Feel free to change this. Tip: If you want the width of the dropdown content to be as wide as the dropdown button, set the width to 100% (and overflow:auto to enable scroll on small screens).

The search field (#myInput) is styled to fit inside the dropdown menu. We have added a search icon, which is placed to the left inside the search field to indicate that this is actually a search field.

Step 3) Add JavaScript:


/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction() {

function filterFunction() {
  var input, filter, ul, li, a, i;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  div = document.getElementById("myDropdown");
  a = div.getElementsByTagName("a");
  for (i = 0; i < a.length; i++) {
    if (a[i].innerHTML.toUpperCase().indexOf(filter) > -1) {
      a[i].style.display = "";
    } else {
      a[i].style.display = "none";
