They show as a list on the index page, and on individual examples they
show in a three-js style sidebar. For now, this is disabled completely
on mobile. Examples can still be opened in 'standalone' mode to get rid
of the sidebar.
Note: the 'view code' link won't work until after these changes are
merged.
There's a small impact on authoring examples: each one needs to live in
a folder with a README.md. At a minimum, the readme needs to look like
this:
```md
---
title: My Example
component: ./MyExample.tsx
---
Here is a 1-liner about my example
```
Optionally, you can:
- Add `hide: true` to the frontmatter to remove the example from the
list (you can skip the description this way)
- Add `order: 3` to control the order in which the example appears.
They're alphabetical otherwise
- Add some more description or links to docs below a `---`. This won't
show in the listing, but will be visible on GitHub and on the example
page itself.
As a follow-up, I'd like to add an 'Open in CodeSandbox' link to each
example. These won't work until we've made a release with these examples
(as our special examples codesandbox is tied to our release process) but
the code is there & ready to go!
Have a play, let me know what you think!
