These components are now available in react-components: https://canonical.github.io/react-components/?path=/docs/components-applicationlayout--docs.

There are some small changes since this PR was created, but if someone would like to take over this PR that would be great!

Thanks for the update, we'll pick this up in the near future. Might be something for @Kxiru

Thank you @huwshimi for your implementation and suggestions. This was a great PR to use for reference and we have now successfully incorporated some Application Layout components into LXD-UI. I will now close this PR.
Thanks again!
