Superset UI panel components

[cvrnogueira]

Hello Superset-ui Community!

I was reading some posts on medium and then I found this one: https://medium.com/airbnb-engineering/supercharging-apache-superset-b1a2393278bd#_=_ that talks a bit about the airbnb dataportal and show some images of dashboards powered using superset ui.
In the first picture I pasted, the author of the post wrote that " the header and left hand panel are powered by @superset-ui". On the second picture the author also say the panel is made using superset ui components. Moreover looking at the documentation and the repo I could not find indications of these panel components. Are they not open source? Does someone know a project-example where they are used? :)
I think they are really nice components and I wanted to have a look

Thank you!
