Accordion component | Commodore

[AlbyIsCoding]

We need an Accordion component like the one in the picture below. The Accordion should handle x amount of elements and picture the below shows how each element should look.

Potential architecture (get inspiration from Radix UI Primitives https://github.com/radix-ui/primitives):

• Accordion that's parent and has callback method onExpand
• AccordionItem
• AccordionContent
• AccordionMessage (the yellow note at the bottom of the card. May be redundant if we can use Panel component for this instead)

Other stuff to think about:

• More than one Accordion should be open at the same time on default (Lay up code so it's easy to choose between more open at once or only 1 open at the same time).
• The arrow down symbol needs to turn from pointing to right to pointing down when clicked.
• Card shadow
• Background colors

Questions:

onExpand could be nullable, if no onExpand method defined card is always expanded? Should we support not having expand method?
