jQuery slideUp – How to Slide Up and Hide an Element Using jQuery

We can use jQuery slideUp() method to hide a div in HTML. The jQuery slideUp() method will slide the element out of view and then hide it.

$('#div1').slideUp();

You can also enter milliseconds as a parameter in the slideUp() method to change the speed at which the slide up happens.

$('#div1').slideUp(1000);

The default speed is 400 milliseconds. In the example above, the div would slide up and out of view at 1000 milliseconds, or 1 second.

Let’s take a look at a very simple example below.

Let’s say we have the following HTML:

<div id="div1">
  <div id="div2"></div>
  <div id="div3"></div>
</div>

To hide #div3 we could use the jQuery slideUp() method

$('#div3').slideUp();

If you are using WordPress, don’t forget to change the $ to jQuery as below:

jQuery('#div3').slideUp();

Let’s take a look at another example below.

Using the jQuery slideUp Method to Start a Simple Navigation Bar

In this example, we will build the start to a nav bar. The navigation menu will work by hovering over a menu item, and then showing new menu items below the div you hovered over.

Here is the HTML and CSS setup:

<style>.example-menu{ height: 220px; } 
.menu-item-container { position: relative; }
#menu-item1 { position: relative; display: inline-block; } 
.menu-items { display: block; padding: 10px 14px; border: 1px solid #444; background: #fff; text-decoration: none; } 
.menu-sub-items { position: absolute; display: none; }
</style>
<div class="example-menu">
  <div class="menu-item-container">
    <div id="menu-item1" class="menu-items">About</div>
    <div id="menu-sub-item1" class="menu-sub-items">
      <a class="menu-items" href="#">Who We Are</a><a class="menu-items" href="#">Staff</a><a class="menu-items" href="#">Contact Us</a>
    </div>
  </div>
</div>

In our JavaScript code, we will make use of the jQuery hover() method first. When the user hovers over the “About” menu item, we will then use the jQuery slideDown() method to show the sub menu that was hidden.

The final part to this example will be to hide the sub-menu again when the user’s mouse leaves the menu. We will use the jQuery mouseleave() method to do this.

Once we leave the sub-menu, we will use the jQuery slideUp() method to hide the sub menu.

Here is the JavaScript code:

$("#menu-item1").hover(function(){
  $("#menu-sub-item2").hide();
  $("#menu-sub-item1").slideDown();
});

$(".menu-item-container").mouseleave(function(){
  $("#menu-sub-item1").slideUp(100);
});

The final code and output for this example of using the jQuery slideUp method to start a simple navigation bar is below:

<style>.example-menu{ height: 220px; } 
.menu-item-container { position: relative; }
#menu-item1 { position: relative; display: inline-block; } 
.menu-items { display: block; padding: 10px 14px; border: 1px solid #444; background: #fff; text-decoration: none; } 
.menu-sub-items { position: absolute; display: none; }
</style>
<div class="example-menu">
  <div class="menu-item-container">
    <div id="menu-item1" class="menu-items">About</div>
    <div id="menu-sub-item1" class="menu-sub-items">
      <a class="menu-items" href="#">Who We Are</a><a class="menu-items" href="#">Staff</a><a class="menu-items" href="#">Contact Us</a>
    </div>
  </div>
</div>

<script>

$("#menu-item1").hover(function(){
  $("#menu-sub-item2").hide();
  $("#menu-sub-item1").slideDown();
});

$(".menu-item-container").mouseleave(function(){
  $("#menu-sub-item1").slideUp(100);
});

</script>
