In the third installment of our drag-and-drop series, we delve into the crucial aspect of monitoring drag-and-drop interactions within your React applications. Monitoring these interactions ensures a responsive and intuitive user experience, giving you the ability to track and react to drag events as they unfold.

We’ll start by reviewing what we’ve implemented so far, then explore how to visually indicate when a card or column is being dragged over. We’ll cover the use of card placeholders to enhance visual feedback, and dive into the Monitoring API to validate data as cards are moved. Finally, we’ll demonstrate how to efficiently move cards within a column, ensuring that your application remains both functional and user-friendly.

*Timeline:*

- 00:12 - What we have built
- 01:16 - Indicate dragging over a card
- 06:23 - Indicate dragging over a column
