This component has been moved to anypoint-web-components/awc.

A modern port of iron-collapse element. It creates a collapsible block of content. By default, the content will be collapsed. Use opened or toggle() to show/hide the content.

The element adjusts the max-height/max-width of the collapsible element to show/hide the content. Avoid putting padding/margin/border on the collapsible directly, and instead put a div inside and style that.
