jQuery UI Sortable
jQuery UI Sortable is a JavaScript library that enables drag-and-drop reordering of elements in a list or grid on a web page. It is part of the jQuery UI suite, providing an interactive way for users to sort items by dragging them with a mouse or touch input. The library handles events like start, stop, and update, making it easy to integrate with backend systems to save the new order.
Developers should use jQuery UI Sortable when building web applications that require user-friendly list or grid reordering, such as admin dashboards, task management tools, or content management systems. It is particularly useful for projects already using jQuery, as it integrates seamlessly and reduces development time compared to building custom drag-and-drop functionality from scratch. However, for modern applications, consider more lightweight or framework-specific alternatives due to jQuery's declining usage.
