Show/Hide Toggle a widget using jQuery in WordPress

How to: show/hide a widget in WordPress with jQuery

By Austin on May 11, 2009

In a previous post I talked about how to show/hide a single div html code with a search inside. Today I’d like to show you how I implemented jQuery into my new theme.

As seen in the current theme, I am using jQuery to animate the show/hide or as known as the css style display: none;.

Since I am using a custom child theme on my site, and have Hybrid theme as my parent, the widgets or sidebar section is different than may be in your theme. But just apply the the style’s as follows to your theme.

First make sure that your WordPress site is calling jQuery, by plugging in this code into your header.php file above the <?php wp_head(); ?> text:

<?php wp_enqueue_script('jquery'); ?>

Then anywhere above the </head >, plug this code in:

<script type="text/javascript">
function toggleWidgets() {
	$('#primary h3.widget-title').addClass('plus');

	$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

}
$(document).ready(function() {
	toggleWidgets();
}
</script>

That’s it. Pretty simple huh.

So lets go over what the code does.

$('#primary h3.widget-title').addClass('plus');

This line finds all <h3> tags with the class widget-title inside the ID parameter of #primary and adds a class of plus.

Then

$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

Will apply a click function. When the H3 tag is clicked it will remove the class plus and add the class minus.

Then the code that says .next will then toggle the “next” element after the <h3> title.

        Doesn’t work for me. I don’t see the class added. I have the last jquery installed, I even tried the noConflict just in case and nothing.
