Spielwiese
The sbb-accordion is a component which acts as a container
for one or more sbb-expansion-panel.
<sbb-accordion>
<sbb-expansion-panel>
<sbb-expansion-panel-header>Header 1</sbb-expansion-panel-header>
<sbb-expansion-panel-content>Content 1</sbb-expansion-panel-content>
</sbb-expansion-panel>
<sbb-expansion-panel>
<sbb-expansion-panel-header>Header 2</sbb-expansion-panel-header>
<sbb-expansion-panel-content>Content 2</sbb-expansion-panel-content>
</sbb-expansion-panel>
</sbb-accordion>
Interaction
The multi property, if set, allows having more than one sbb-expansion-panel expanded at the same time.
<sbb-accordion multi> ... </sbb-accordion>
Style
The component has two different sizes, l (default) and s, which can be changed using the size property.
The property overrides the size value of any inner sbb-expansion-panel.
<sbb-accordion size="s"> ... </sbb-accordion>
The component has a titleLevel property, which is proxied to each inner sbb-expansion-panel-header, and can be used
to wrap the header of each sbb-expansion-panel in a heading tag; if the property is unset, a div is used.
In the following example, all the sbb-expansion-panel-header would be wrapped in a h3 heading tag.
<sbb-accordion title-level="3">
<sbb-expansion-panel>
<sbb-expansion-panel-header>Header 1</sbb-expansion-panel-header>
<sbb-expansion-panel-content>Content 1</sbb-expansion-panel-content>
</sbb-expansion-panel>
...
</sbb-accordion>
