Accordion group

The accordion group permits multiple accordions to be used together, as well as multiple accordion groups on a page.

Implementation

The accordion component is wrapped in:

<ul class="au-accordion-group" id="accordion-group-X">
  <li>
    ACCORDION
  </li>
</ul>

Open/close all controls

The open/close controls are placed before the accordion group and teh JavaScript references the accordion group ID, as described above.

<div class="au-accordion-group__controls">
    <button class="au-accordion-group__control" onclick="return AU.accordion.Open(document.querySelector('#accordion-group-X').getElementsByClassName('js-au-accordion'))">Open all</button>
    <button class="au-accordion-group__control" onclick="return AU.accordion.Close(document.querySelector('#accordion-group-X').getElementsByClassName('js-au-accordion'))">Close all</button>
</div>

Multiple accordion groups

To ensure that controls do not operate the equivalent accordion across groups, use unique IDs on the accordion body and match aria-control references.

For example accordion-1-1 below:

<section class="au-accordion">
    <button class="au-accordion__title js-au-accordion au-accordion--closed" aria-controls="accordion-1-1"
    aria-expanded="false" onclick="return AU.accordion.Toggle( this )">
        TITLE
    </button>

    <div class="au-accordion__body au-accordion--closed" id="accordion-1-1">
        <div class="au-accordion__body-wrapper">
            BODY CONTENTS
        </div>
    </div>
</section>

Variants

Whilst the behaviour of accordion groups is consistent across types, the following variants exist to suit applications.

Note that variant classes should be applied to the .au-accordion-group. Accordion variant classes are applied to the au.accordion elements directly.

Default

Standard group behaviours and styles

Flush

The accordions are grouped togther without spacing. This is particularly suited to applications and can be extended to include rows/tablular data or similar.

Tokens

The following CSS custom variables allow customisation:

  1. –accordion-control-link-text: accordion control link colour
