The sbb-expansion-panel-header is a component which is meant to be used as a header
in the sbb-expansion-panel,
acting as a control for an expanding / collapsing content, like a native <summary> tag.

<sbb-expansion-panel-header>Header</sbb-expansion-panel-header>

Slots

The component is internally rendered as a button, and it is possible to provide text via an unnamed slot.
On the left side, a toggle icon is displayed; it flips based on the host's aria-expanded property.

The component can optionally display a sbb-icon at the component start using the iconName
property or via custom content using the icon slot.
If using the SBB icons, the icon should be a medium size icon.

<sbb-expansion-panel-header icon-name="swisspass-medium">Header</sbb-expansion-panel-header>

States

The component can be displayed in disabled state using the self-named property.

<sbb-expansion-panel-header disabled>Header</sbb-expansion-panel-header>

Events

When the element is clicked, the toggleExpanded event is emitted.
