I added cq:actions to sub component and it started working however moving cards inside container is not smooth operation, it's so flaky and doesn't move cards very easily, not a great user experience.
Is it possible to pre-populate parsys with the sub component as soon as user configures parent container component?
We are not using AEM responsive grid, we have got custom grid. We are building custom component that contains child components and these child components are also custom components. Basically custom list component with custom card components, both configurable.
