Feature Request: Support for Variable Item Heights

[ruveydayilmaz]

Description:

Currently, the package only supports a fixed item height via the itemHeight prop. However, it would be highly beneficial to have support for different item heights, as many use cases require varying heights for grid items.

Proposed Solution:

• Add support for variable item heights based on the individual item's data.
• Allow each item to define its height dynamically (e.g., through a function or by providing a height property in the data for each item).
• Ensure that the grid layout and drag-and-drop functionality work smoothly with different item heights.

Example Use Case:

<DraggableGrid
  numColumns={numColumns}
  renderItem={renderItem}
  data={data}
  onDragRelease={handleDragRelease}
  itemHeight={(item) => item.height} // Dynamically set the height per item
/>
