/**
|
|
* Accordion-folding functionality.
|
|
*
|
|
* Markup with the appropriate classes will be automatically hidden,
|
|
* with one section opening at a time when its title is clicked.
|
|
* Use the following markup structure for accordion behavior:
|
|
*
|
|
* <div class="accordion-container">
|
|
* <div class="accordion-section open">
|
|
* <h3 class="accordion-section-title"></h3>
|
|
* <div class="accordion-section-content">
|
|
* </div>
|
|
* </div>
|
|
* <div class="accordion-section">
|
|
* <h3 class="accordion-section-title"></h3>
|
|
* <div class="accordion-section-content">
|
|
* </div>
|
|
* </div>
|
|
* <div class="accordion-section">
|
|
* <h3 class="accordion-section-title"></h3>
|
|
* <div class="accordion-section-content">
|
|
* </div>
|
|
* </div>
|
|
* </div>
|
|
*
|
|
* Note that any appropriate tags may be used, as long as the above classes are present.
|
|
*
|
|
* In addition to the standard accordion behavior, this file includes JS for the
|
|
* Customizer's "Panel" functionality.
|
|
*
|
|
* @since 3.6.0.
