Draggable Element must have an item slot
When creating a draggable element, it is important to provide an item slot for it to occupy. The item slot serves as the target where the draggable element can be dropped or placed.
Example:
In this example, we have a draggable element represented by the .draggable class. It has the dragabble="true" attribute applied to make it draggable.
Below the draggable element, we have an item slot represented by the .item-slot class. The ondrop and ondragover event handlers are applied to allow dropping on the item slot.
The JavaScript functions, allowDrop() and drop(), handle the dragging and dropping functionality. The allowDrop() function prevents the default behavior when the draggable element is being dragged over the item slot. The drop() function appends the dragged element to the item slot when it is dropped.
By providing the item slot, we ensure that the draggable element has a target to be dropped on, allowing for a more interactive and intuitive user experience.
