Data and privacy

This card uses its configured properties and live card data.

Properties

For theme, background, accent and position, see Common properties.

Set static properties in params. Bind data to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in params. Nested rows describe the contents of their parent property.
