// --- 'all' mode (default) ---
// rowCount = total number of all currently visible nodes
// (roots + expanded children). Page count is based on this.
// Best when you want consistent page sizes regardless of expansion state.
const allModeProvider = new CAPITreeServerDataProvider({

// --- 'root' mode ---
// rowCount = number of root-level nodes only.
// Page count is based on root nodes. Children don't count toward pagination.
// Best for category trees where you want exactly N top-level items per page.
const rootModeProvider = new CTreeClientDataProvider({

// Explicit typing
const mode: TreePaginationMode = 'root'

// On the server side (tree-api-server-side) — paginateBy arrives as a string:
const paginateBy = (query.paginateBy as TreePaginationMode) ?? 'all'

// Use it to decide whether rowCount counts all nodes or only roots:
const rowCount = paginateBy === 'root'
