DragSelect is a lightweight, dependency‑free JavaScript library that adds OS‑style drag‑select and drag‑and‑drop functionality to any web page. It lets developers easily make groups of elements selectable, movable, and accessible (including keyboard and touch support) with a highly customizable API, making it ideal for file managers, dashboards, or any interactive UI that needs multi‑item selection. Suitable for front‑end developers building rich, performant web applications without pulling in extra frameworks.
