Recently, we encountered a challenge in developing interactive interfaces: the need to create movable blocks that function as dynamic menus, allowing buttons to be dragged in any direction and organized in a row.
After researching various libraries, we identified that DnD Kit offered the best solution. Its detailed documentation and practical examples allowed us to make the most of its key features, such as useDraggable to move elements and useDroppable to manage their insertion into specific areas. Additionally, the customization of animations and the row layout were decisive factors in its selection.
For the implementation, we started by installing the necessary libraries and configuring sensors in the application context, enabling detection of both mouse and touch screen gestures. We chose to use collisionDetection=pointerWithin to optimize interaction based on the pointer position and adjacent objects.
The main component, DndRoot, manages the state of the active block when dragging starts (handleDragStart), and resets it when finished (handleDragEnd). Additionally, the handleDragOver event detects if the block is over a valid drop area.
The organization of the buttons was done using a state that stores them with properties such as order and row number, facilitating their storage in databases. For each row, we implemented the DndRow component, where SortableContext is applied for horizontal reordering.
In our system, the positions of the buttons changed visually when dragged, but they were not updated in the state until the user released the button. Therefore, we developed specific functions to recalculate both the order of elements within a row and the row number when moving multiple buttons between rows.
Finally, we optimized the user experience by adding animations to smooth the transitions when moving the buttons. To achieve this, we used DnD Kit's DragOverlay functionality, which allows rendering a clone of the button while dragging, achieving a fluid animation.
At Q2BSTUDIO, a leading company in development and technological services, we apply this type of innovative solutions to improve the usability of our applications. We specialize in offering efficient and customizable interactive experiences, adapting to the needs of each project. If you are looking to optimize your platform with advanced drag and drop functionality, our team can help you implement intuitive and scalable solutions.
This development demonstrates how, with the right tools and a well-planned architecture, it is possible to significantly improve user interaction in digital interfaces.
