In my application, I have custom logic based on which i decide whether a target cell is valid drop target or not. I have overriden the isValidDropTarget method to add the custom logic and return false when I do not want a node to act as a container\nMy app is similar to the GraphEditor example in terms of overall layout. \nNow my problem is that when I drag a cell from the library panel to the main graph panel over another symbol, it always highlights the target cell with the blue outline (even if it is not a valid drop target)


Whereas when I drag and drop a cell to a void space in the graph and then I drag it over a target cell (my overriden method is called) and the target cell is or is not highlighted as per the return value of my method.


I want to understand how I can replicate the same functionality of highlighting (based on the isValidDropTarget method) even in case I am dragging and hovering the cell from the library panel directly over a target cell?

mxUtils.makeDraggable returns an mxDragSource. Override mxDragSource.getDropTarget or set mxDragSource.prototype.highlightDropTargets to false.
