React SDK 0.8.18 adds NxLookupField.selectAllOptions, NxLookupDialog.selectAllRows and ResourceTable.onVisibleColumnsChange. Selection loaders must return all authorized results for the current query, honor cancellation and reject partial results. Apply/Cancel behavior remains unchanged. Visible columns may guide server search but never replace authorization before pagination. Adopt the matching Core host. See the UI component guide and package artifact.
