I have a simple Accordion menu whicih I got from jsfiddle only. I want to make it nested.
Click jsfiddle
Posting the code in case jsfiddle is not working:
HTML
<div class="accordion-expand-holder">
<button type="button" class="open">Expand all</button>
<button type="button" class="close">Collapse all</button>
</div>
<div id="accordion">
<h3>Section 1</h3>
<div>
<p>Para 1</p>
</div>
<h3>Section 2</h3>
<div>
<p>Para 2</p>
</div>
<h3>Section 3</h3>
<div>
<p>Para 3</p>
<ul>
<li>List item one</li>
<li>List item two</li>
<li>List item three</li>
</ul>
</div>
<h3>Section 4</h3>
<div>
<p>para 4 - 1</p>
<p>Para 4 - 2</p>
</div>
JQuery:
$(function () {
$("#accordion").accordion({
collapsible:true,
active:false
});
var icons = $( "#accordion" ).accordion( "option", "icons" );
$('.open').click(function () {
$('.ui-accordion-header').removeClass('ui-corner-all').addClass('ui-accordion-header-active ui-state-active ui-corner-top').attr({
'aria-selected': 'true',
'tabindex': '0'
});
$('.ui-accordion-header-icon').removeClass(icons.header).addClass(icons.headerSelected);
$('.ui-accordion-content').addClass('ui-accordion-content-active').attr({
'aria-expanded': 'true',
'aria-hidden': 'false'
}).show();
$(this).attr("disabled","disabled");
$('.close').removeAttr("disabled");
});
$('.close').click(function () {
$('.ui-accordion-header').removeClass('ui-accordion-header-active ui-state-active ui-corner-top').addClass('ui-corner-all').attr({
'aria-selected': 'false',
'tabindex': '-1'
});
$('.ui-accordion-header-icon').removeClass(icons.headerSelected).addClass(icons.header);
$('.ui-accordion-content').removeClass('ui-accordion-content-active').attr({
'aria-expanded': 'false',
'aria-hidden': 'true'
}).hide();
$(this).attr("disabled","disabled");
$('.open').removeAttr("disabled");
});
$('.ui-accordion-header').click(function () {
$('.open').removeAttr("disabled");
$('.close').removeAttr("disabled");
});
});
CSS:
body {
font-family:Arial, Tahoma, Verdana, Helvetica, sans-serif;
font-size:65%;
}
.accordion-expand-holder {
margin:10px 0;
}
.accordion-expand-holder .open, .accordion-expand-holder .close {
margin:0 10px 0 0;
}
I want these menus to be nested. I am new to JQuery please be gentle.
回答1:
Just change the ID to a class and then nest them and make sure that autoHeight:false when instantiating the accordion.
Working demo here http://jsfiddle.net/hEApL/147/
