I have a tree with regular nodes and also some nodes that have Class1 added to them:
addClass: "custom1"
How can I prevent dropping on custom1 nodes and allow dropping on all other (regular) nodes?
Add a line to the onDrop handler to check the data.addClass of the target node:
onDrop: function(node, sourceNode, hitMode, ui, draggable) {
if( node.data.addClass == 'custom1'){
return;
}
// move the source
}
