Thanks for taking this one on. Here are some changes I'd suggest.

One teeny-tiny change and we're good to go. The very first heading should be ## Overview instead of ## Description. DM me when you want me to re-review and I'll approve it.

[marissahuysentruyt]

Lots of questions! I think this is probably good to go, but there's quite a bit of repetitive docs that I want your opinion on if we need.

[marissahuysentruyt]

Was there more to delete in this section? Or should we update this documentation to talk about the direction="vertical" property? Right now there's lots of duplicate content, but the sp-tabs` demos are different/vertical.

[marissahuysentruyt]

@cdransf just wanted to double check on this comment. Any thoughts on updating the docs here to mention the direction="vertical" stuff?

[cdransf]

Oops, yep! Adding:

Vertical tabs should be used when horizontal space is more generous and when the list of sections is greater than can be presented to the user in a horizontal format. Vertical tabs are enabled by setting the direction attribute to vertical on sp-tabs.

I left a screenshot and a slack message for you about the funky placement of quiet/quiet+compact.
