Details View: current limitation
Details View is intended for larger record content than a small popover. Its settings and templates are visible in the v9 tree, but the current development version has an unresolved instance-selection problem in the Interactions → Show details view action.
Use a popover for the documented examples
Section titled “Use a popover for the documented examples”Configure Region / Marker → Interactions → Show popover, and place your content in the corresponding Popover template. See Tooltips and popovers.
For a design that must navigate to a separate page, use an appropriate verified link action and test it on the frontend. Editor navigation restrictions can differ from normal visitor navigation.
What remains configurable
Section titled “What remains configurable”You can inspect the Details component’s available Settings, Styles, and Code sources. Its size/layout and content configuration are separate from the action that chooses which instance to open.
A correct-looking template or selected tree row does not prove that the click action will open that same instance. Keep an unpublished draft for experiments and verify the behavior after the instance-linking issue is fixed.
Existing sites
Section titled “Existing sites”This limitation concerns the current v9 authoring/action path. It is not a statement that every existing v8 Details setup has stopped working. Preserve a working v8 publication while reviewing a migration draft, and compare its actual frontend behavior before replacing it.
See Upgrading from v8 and Publish and History.
