Question

Well, this question is next version of my earlier question.

As I have all links collapsed, I want to create one button OR link saying “Show All”, on clicking it will make all links active in accordion i.e. I want to view data of all links. Also need to create one button OR link saying “Hide All” which will make collapsed state as earlier.

Collapsed State

+++++++++++++++++++++++++++++++++++++++
+   Link 1                            +
+   Link 2                            +
+   Link 3                            +
+   Link 4                            +
+++++++++++++++++++++++++++++++++++++++

Should get after clicking “Show All”

+++++++++++++++++++++++++++++++++++++++
+   Link 1                            +
+     Link 1 line 1                   +
+     Link 1 line 2                   +
+     Link 1 line 3                   +
+   Link 2                            +
+     Link 2 line 1                   +
+     Link 2 line 2                   +
+     Link 2 line 3                   +
+   Link 3                            +
+     Link 3 line 1                   +
+     Link 3 line 2                   +
+   Link 4                            +
+     Link 4 line 1                   +
+     Link 4 line 2                   +

How to do this?

Answer 1

Here is your solution to expand and collapse all content panels.

function expandAll() {
    $('#accordion h3').removeClass('ui-state-default')
        .addClass('ui-state-active')
        .removeClass('ui-corner-all')
        .addClass('ui-corner-top')
        .attr('aria-expanded', 'true')
        .attr('aria-selected', 'true')
        .attr('tabIndex', 0)
    .find('span.ui-icon')
        .removeClass('ui-icon-triangle-1-e')
        .addClass('ui-icon-triangle-1-s')
    .closest('h3').next('div')
        .show();

    $('.expand').text('collapse all').unbind('click').bind('click', collapseAll);

    $('#accordion h3').bind('click.collapse', function() {
        collapseAll();
        $(this).click();
    });
}

function collapseAll() {
    $('#accordion h3').unbind('click.collapse');

    $('#accordion h3').removeClass('ui-state-active')
            .addClass('ui-state-default')
            .removeClass('ui-corner-top')
            .addClass('ui-corner-all')
            .attr('aria-expanded', 'false')
            .attr('aria-selected', 'false')
            .attr('tabIndex', -1)
        .find('span.ui-icon')
            .removeClass('ui-icon-triangle-1-s')
            .addClass('ui-icon-triangle-1-e')
        .closest('h3').next('div')
            .hide();

    $('.expand').text('expand all').unbind('click').bind('click', expandAll);

    $('#accordion').accordion('destroy').accordion();
}
