Question

I have created an accordion using jQuery which collapses fine when the user clicks a 2nd option but I would also like to have the option to collapse the open pane by clicking again on the header. How can I do this?

Here is my existing jQuery for the creation of the accordion:

$("#accordion").tabs("#accordion div.pane", {tabs: 'h2', effect: 'slide', initialIndex: null, });

Here is the HTML:

<div id="accordion">

    <h2>Heading 1</h2>
    <div class="pane">... pane content ...</div>
    
    <h2>Heading 2</h2>
    <div class="pane">... pane content ...</div>
    
    <h2>Heading 2</h2>
    <div class="pane">... pane content ...</div>

</div>

Answer 1

//Initialize a accordion with the collapsible option specified.
$( ".selector" ).accordion({ collapsible: true });
//Get or set the collapsible option, after init.
//getter
var collapsible = $( ".selector" ).accordion( "option", "collapsible" );
//setter
$( ".selector" ).accordion( "option", "collapsible", true );
