Which data types can a tree grid layout reference?

The tree grid layout is designed to display hierarchical data structures, making it suitable for use with data types that can represent such structures effectively. The first choice is correct because a page list allows for multiple entries and can encapsulate hierarchical data through nested pages. Additionally, a report definition of the summary type can aggregate data and represent it in a way that fits nicely into a tree grid format, as it can group and summarize data entries as needed.

In contrast, the other options reference data types that do not align as closely with the requirements of the tree grid layout. A single page typically represents a single record and does not inherently support multiple hierarchical levels. Data flows, while useful for processing data, do not directly correlate with the tree grid format for displaying data.

Text properties are designed to hold string values and do not have the capacity to represent structures or collections of data necessary for a tree grid. A data page, on the other hand, while it can provide data for a tree grid, typically acts as a wrapper for bringing data into the UI; it's not inherently hierarchical in the way needed for this layout.

Database tables may store hierarchical data but typically do not directly translate to a tree grid layout without further processing or transformation. Service packages are related to integration
