Accordion / Collapsible
Accordion Layout
Common Accordion layout could be treat as the following:
<div class="accordion-list">
<div class="accordion-item">
<div class="accordion-item-toggle">...</div>
<div class="accordion-item-content">...</div>
</div>
<div class="accordion-item accordion-item-opened">
<div class="accordion-item-toggle">...</div>
<div class="accordion-item-content">...</div>
</div>
<div class="accordion-item">
<div class="accordion-item-toggle">...</div>
<div class="accordion-item-content">...</div>
</div>
...
</div>
Where
accordion-list
- list of accordion items set. Optional classaccordion-item
- single accordion item. Requiredaccordion-item-toggle
- link to expand/collapse accordion item content. Requiredaccordion-item-content
- hidden accordion item content. Required
accordion-item-opened
- single opened accordion item
Collapsible Layout
If you want to use single separate collapsible element you may just omit “accordion-list” wrapper element:
<!-- Single collapsible element -->
<div class="accordion-item">
<div class="accordion-item-toggle">...</div>
<div class="accordion-item-content">...</div>
</div>
<!-- Another separate collapsible element -->
<div class="accordion-item">
<div class="accordion-item-toggle">...</div>
<div class="accordion-item-content">...</div>
</div>
Accordion List View
If you use list view as accordion you may use “item-link” element instead of “accordion-toggle”:
<div class="list accordion-list">
<ul>
<li class="accordion-item">
<a href="" class="item-link item-content">
<div class="item-inner">
<div class="item-title">Item 1</div>
</div>
</a>
<div class="accordion-item-content">Item 1 content ...</div>
</li>
<li class="accordion-item">
<a href="" class="item-link item-content">
<div class="item-inner">
<div class="item-title">Item 2</div>
</div>
</a>
<div class="accordion-item-content">Item 2 content ...</div>
</li>
</ul>
</div>
Example
<!-- List View -->
