Accordion: Enable synched accordion interactions (configurable)

[mfranzke]

Regarding the accordion component we're currently missing the configurability for the component to either let the included different accordion elements behave individually or getting "synced" interactions by closing the open element in case that somebody opens another one ("typical accordion effect").

#386 might be a prerequisite for this issue.

Hey @mfranzke,

do you expect the component to have an additional group attribute and communicate via events or some kind of wrapper component ?
If I am not wrong currently having two accordions on the same page they don't know from each other.
Currently the the solutions that I have in mind have an additional attribute for enabling the sync behaviour plus some kind of key to identify accordions belonging to the same group or having a wrapper which takes care of grouping multiple accordions together ?
If I am on the right tracker I could take over this issue.

Hey @ewatch,

that sounds great, thanks a lot.

I would prefer a wrapper (like e.g. db-accordings) that would as well bring the logical grouping aspect for included db-accordion elements, comparable e.g. to an (un)ordered list that groups list-items in the standard HTML stack.

Hey @mfranzke,

alright, I will take care and make a PR soon.
