The tree of named items along the left of an ExApp page. The ExApp supplies the tree. The selected item is the page on display. It plays the same role as the navigation in Nextcloud Files. An ExApp that does not use App navigation shows its own page instead.
_Avoid_: Top Menu, sidebar, NcAppNavigation
+**Dialog**:
+A modal window on an ExApp page, in the same Nextcloud theme as that page. It does not require App navigation. The page waits for the user's choice; that choice is not a server request. The heading, the message, and the button word are plain text. The heading may be omitted. The fixed buttons are the English words OK and Cancel. One of three kinds: a Message (short text at info, warning, or error, dismissed with one button), a Confirm (yes or no; the agreeing button may be destructive), or a Prompt (one entered value, or cancelled). A Prompt with no value cannot be agreed. A successful Prompt value has no surrounding spaces. The caller may supply a starting value. A Prompt field has no label of its own; the message is the text above it.
+_Avoid_: popup, browser alert/confirm/prompt, Notification, toast, HTML message
+
**Top Menu visibility**:
Whether the ExApp app icon in the Nextcloud top menu is shown to all logged-in users or to Nextcloud admins only. Configured per deploy via env `TOP_MENU_ADMIN_REQUIRED` (`0` or `1`); the ExApp passes the value to AppAPI when registering the top-menu entry on enable. Independent of route `access_level` in info.xml and of Required Groups.
_Avoid_: route access_level, Required Groups, AppAPI group ACL

- **Groups** — Users and Groups reads: `UserGroups`, `GroupMembers`, `ListGroups` (no search/paging). Directory calls (`GroupMembers` / `ListGroups`) run as the Credentials user and need an admin or subadmin
- **Access Gate** — optional Required Groups enforcement (`Wrap` + `Check`), English denied HTML for browsers (200 + `frame-ancestors 'self'`), positive membership cache; default skip for lifecycle paths and **`/js/`** top-menu scripts; env helpers for `REQUIRED_GROUPS` / `REQUIRED_GROUPS_CACHE_SECONDS`

The selected item is the `item` query parameter (override with `SelectKey`). Other query parameters, including a Visit folder, are left in place. By default the shell loads the Nextcloud theme stylesheets, paints `--image-background`, and copies the surrounding page’s `data-theme-*` markers; set `DisableTheme` to skip the stylesheets. An item may set `Icon` to a same-origin image URL. `NextcloudIcons` names the core SVGs Nextcloud already serves (`NextcloudIcons.Folder`, `NextcloudIcons.Password`, and the rest). Not mounting the handler keeps the ExApp’s own page. Lifecycle routes, HaRP startup, and Top Menu registration stay in the ExApp.
