Jquery Drop Down Menu for WordPress

Step 1: Jquery

The following script contains comments explaining which jQuery actions are being performed.

$(document).ready(function(){

	$("ul.subnav").parent().append("<span></span>"); //Only shows drop down trigger when js is enabled (Adds empty span tag after ul.subnav*)

	$("ul.topnav li span").click(function() { //When trigger is clicked...

		//Following events are applied to the subnav itself (moving subnav up and down)
		$(this).parent().find("ul.subnav").slideDown('fast').show(); //Drop down the subnav on click

		$(this).parent().hover(function() {
		}, function(){
			$(this).parent().find("ul.subnav").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
		});

		//Following events are applied to the trigger (Hover events for the trigger)
		}).hover(function() {
			$(this).addClass("subhover"); //On hover over, add class "subhover"
		}, function(){	//On Hover Out
			$(this).removeClass("subhover"); //On hover out, remove class "subhover"
	});

});

Step 2: CSS

/* Top Menu */

ul.topmenu {    list-style: none;padding: 0;margin: 0;float: left;width: 100%;    background: #205528;font-size: 1.2em; height: 34px;  }

ul.topmenu li {    float: left;    margin: 0;    padding: 0 5px;    position: relative; }

ul.topmenu li a{    padding: 10px 5px;    color: #fff;    display: block;    text-decoration:bold;    float: left;}

ul.topmenu li a:hover{  text-decoration:underline;opacity:0.6;}

ul.topmenu li .select a{    background: #ffffff;    color:#016CA3;    }

ul.topmenu li a:focus{    background: #ffffff;    color:#016CA3;   }

/*–Drop down trigger styles–*/

ul.topmenu li span {     width: 10px;    height: 20px;    float: left;    margin:5px ;

background:url(http://ossbooks.com/wp/wp-content/uploads/2010/04/more_icon.png) no-repeat center;

}

ul.topmenu li span.sub :hover {background:#016CA3; cursor: pointer;opacity=90; } /*–Hover effect for trigger–*/

ul.topmenu li ul.subnav {list-style: none;position: absolute; left: 0; top: 30px;background: #333;margin: 0; padding: 0;

display: none;    float: left;    width: 160px;    z-index:1000;    border: 1px solid #A5C2E3;}

ul.topmenu li ul.subnav li a:hover{background:#6bc044 url(http://ossbooks.com/wp/wp-content/uploads/2010/02/dropdown-on.gif) no-repeat 7px 8px;}

ul.topmenu li ul.subnav li{margin: 0; padding: 0;border-bottom: 1px solid #A5C2E3; clear: both;    width: 160px;}

html ul.topmenu li ul.subnav li a {float: left;    width: 140px;background: #fff url(http://ossbooks.com/wp/wp-content/uploads/2010/02/dropdown-off.gif) no-repeat 10px center;   color: #333;padding:10px 0 10px 20px;}

html ul.topmenu li ul.subnav li:hover { background: #222;}

/* Top Menu End*/

<div>

<ul>

//acc_id refers category id

<?php $acc_id = “29,9,12,11,13”; $accids = explode(“,”, $acc_id);

//Get size of array

$asize=sizeof($accids);

for($i=0; $i<$asize; $i++)

{

$display=get_cat_name($accids[$i]);

echo  “<li><a>”.$display.”</a>”; ?>

<ul><?php wp_list_categories(‘orderby=id&show_count=0&use_desc_for_title=0&child_of=’.$accids[$i].’&title_li=’);?></ul>

</li>

<?php } ?>

</ul>

1. Enqueue Jquery

The first thing you want to do is to get Jquery to load WordPress comes with a version of Jquery included so its generally best to load that> The function to load javascript libraries and plugins is wp_enqueue-script. The code to load the jQuery and the jQuery Cycle plugin is below

<?php wp_enqueue_script('jquery.cycle.all.min','/wp-content/themes/upsidedowncity_v_3/jquery.cycle.all.min.js',array('jquery')); ?>
<?php wp_enqueue_script('jquery_script','/wp-content/themes/upsidedowncity_v_3/jquery_script.js'); ?>
<?php wp_head(); ?>


Place this code right above the “wp_head();” line your header.php file.
 Write the css code for featured post sideshow.


/*Featured Post Slide Show @asokkumar.t@gmail.com*/
#featured_posts{
width:960px;
margin-left:-10px;
height:140px;
}

#featured_posts h3{
font-size:12px;
width:255px;
}

#featured_posts ul{

}

#featured_posts ul li{
float:left;
margin:0 9px 0;
}

.slide_cont{
width:835px;
clear:none;
float:left;
margin:0 17px;
}

.slide_cont ul li h3 a, .slide_cont ul li h3 a:hover{
color:#fff;
}

.prev{
display:block;
width:35px;
height:75px;
background: url('images/left_arrow.png') no-repeat center;
cursor:pointer;
float:left;
margin:35px 0 0 10px;
}

.next{
display:block;
width:35px;
height:75px;
background: url('images/right_arrow.png') no-repeat center;
cursor:pointer;
float:right;
margin:35px 10px 0 0;
}

h1, h2, h3, h4, h5, h6{
color:#fff;
background:#000;
font-family:"courier new",courier;
padding:3px 0 3px 5px;
}
