To implement this use case, I would either:
- Create two dashboards – the “simple” one and the “advanced” one. They could be two different dashboards in the left side bar, or two tabs in the same dashboard. The button card has a navigation action or there are custom cards that allow for navigation among dashboard tabs, so you could put a button on the simple dashboard that navigates you to the advanced dashboard
- Implement some sort of collapsing or accordion card.
