W3.CSS Dropdowns


Dropdown Hover

The w3-dropdown-hover class defines an hoverable dropdown element.

The w3-dropdown-content class defines the dropdown part to be displayed.

Example

<div class="w3-dropdown-hover">
  <button class="w3-btn w3-red">Hover Me!</button>
  <div class="w3-dropdown-content w3-border">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</div>

Both the hoverable element part and the dropdown element can be any HTML element.

In the previous example the hoverable part was a <button>, and the dropdown part a <div>.

In the next example the hoverable part is a <p> element, and the dropdown part is a <span>:

Example

<div class="w3-dropdown-hover">
  <p>Hover Me!
  <span class="w3-dropdown-content w3-border">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</div>

Clickable Dropdown

The w3-dropdown-click class is similar to w3-dropdown-hover, except that the dropdown is opened by JavaScript.

  <div id="Demo" class="w3-dropdown-content w3-card">

    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
