Site map
The navigation structure of a model-driven Power App — areas, groups, subareas that define what users see in the left navigation.
The site map of a model-driven Power App is its navigation structure — the left-side menu users see. The hierarchy: areas (top-level groupings, switchable from a button), groups (labelled subdivisions within an area), subareas (the actual navigation items that link to a table's page, a view, a dashboard, a URL, a custom page, or a web resource). Site maps can be role-scoped — different subareas visible to different security roles. The modern site map designer in the maker portal replaced the older XML-based configuration. The site map shapes the daily user experience of the app; deliberate design — group by what users do, not by underlying tables — is one of the most consequential UX investments in a model-driven app.
