Overlay Calcite Panels

[BobCowling2]

I am wondering the proper way to overlay one or more Calcite Panels. The panels should not be side-by-side or stack on top of each other. I would start with an existing panel, the main panel, and then another panels would slide in and overlay the existing panel, not replace it. Then once the overlay panel is closed, the main panel would still be there. 

Right now I have a panel for Find and Explore. This is the main panel that should always be there. The search results panel should slide in and overlay the Find and Explore Panel. Right now they are stacked on top of each other. I know I can do this using CSS positioning and visibility but is there a way to Calcite to do this?

It seems like the Flow Component is what you are looking for. You can use Flow Item components as direct children, and programmatically switch between them based on your needs. Flow Item are essentially wrapped Panel components, so they should have familiar properties, slots, etc.

Here's an example in isolation: Flow example in Codepen

Depending on what you want the experience to look like, you could also explore using a Sheet or a Dialog component, that could be invoked and dismissed as needed.

Thank you. The sheet component is what I was essentially looking for.
