Lovelace: custom sidebar card

Hi all

I’m back on the ha game after a couple of years,
I’m having trouble trying to get this sidebar to show, I’ve done the repo bit via hacs then copied the yaml for resources as on GitHub to the raw config editor in the dashboard I use etc
But can’t find,use the sidebar anywhere. I must be doing something stupid!

My dashboard has 4 views for different floors etc all in sections view,
Anyone help?
TIA

Wow… It was wonderful But the pastebin code expired. Could you give more information on how you did it?

sorry but this is an old post of 2 years ago. I’ve changed my setup over the years
