Up to this point you have examined the HTML5 Drag and Drop API one event at a time. In this topic you put the pieces together and build a complete interactive component — typically a sortable list or a Kanban-style board — where items can be picked up, dragged across containers, and dropped into a new position. The work begins before any code: planning what the component must do, deciding which elements are draggable, which are drop targets, and what data each dragged item carries.
From there you build the markup (draggable="true", container and item structure, data attributes for identifiers), wire up dragstart to stash an identifier on the dataTransfer object, use dragover with preventDefault() to declare a valid drop zone, and finish in drop by moving or reordering the DOM nodes. Just as important is what happens behind the visible interface: the underlying data model — the array or object that represents your list or board — must stay in sync with the DOM, or the component will look correct but behave incorrectly on save, refresh, or re-render. Finally, because pointer-based dragging excludes keyboard and screen-reader users, you add keyboard alternatives, ARIA attributes, and clear visual affordances.
The three videos below approach the same problem from different angles: native browser API, a framework component library, and a reusable framework-level abstraction. While watching, track three things — where state is stored, how each event handler contributes to the interaction lifecycle, and what the implementation does (or fails to do) for users who are not using a mouse. Being able to compare a hand-written implementation to a library-provided one is useful even if your project uses only vanilla JavaScript.
A compact walkthrough of drag-and-drop in plain JavaScript that, based on its title and description, covers both dragging HTML elements around the page and dragging files into the browser, and also mentions using a plugin for added functionality. Expect to see the markup setup, the core event listeners, and the handler logic that moves an element to a new container.
This is the closest match to the hand-coded, framework-free approach used in this course, so it maps directly onto the HTML structure, dragstart, dragover, and drop subtopics without hiding the API behind a library.
A mid-level tutorial from Decoded Frontend on the Angular Material CDK drag-and-drop module, focused specifically on transferring items between multiple lists. It is likely to show connected drop lists, reordering within a list, moving items across lists, and the events the CDK exposes when a drop occurs.
The multi-list scenario is exactly the Kanban-style pattern this topic targets, and because CDK drop handlers require you to update the backing arrays yourself, it illustrates the state-and-data-model subtopic very clearly.
This video builds a minimal draggable element and drop zone in Svelte using the browser's native Drag and Drop API, packaged as reusable Svelte actions. Expect attention to how the native events are attached and cleaned up, and how the same behavior can be applied to many elements without repeating code.
It demonstrates the native API being wrapped into a reusable abstraction, which reinforces the planning subtopic and shows how to keep drag logic separate from component markup and state.
Together these videos reinforce the module outcomes at the point where they come together in a real build. The vanilla JavaScript walkthrough and the Svelte action video both work directly with the native events and the DataTransfer object, supporting MO1, MO2, and MO3 by showing which handler does what and why preventDefault() on dragover matters. The Angular CDK video and the multi-list reordering pattern it demonstrates support MO4, since a working sortable or Kanban component requires that the DOM and the underlying data arrays update in step. None of the videos is a dedicated accessibility lesson, so for MO5 you should watch each implementation critically and note where keyboard operation, focus handling, and ARIA attributes would need to be added before the component could be considered complete.
