Hi Hamid,

Please use command manager to prevent the copy command. please refer to the code example and JSPlayground link below. If we misunderstood your requirement, please provide us more details such as the usecase in which you need to prevent the copy command or more details about your requirement.

Code example:

$("#diagram").ejDiagram({         

            commandManager: {

                commands: {

                    //Command name

                    "copy": {

                        //Command handler

                        canExecute: function copy(args) { return false },

                    }

                }

            },
        });

Hi Hamid,

We have created a mind map sample in which we have disabled the copy of root node using the command manager. Please refer to the code example and JSPlayground link.

Code example:

$("#diagram").ejDiagram({

 

                commandManager: {

                    commands: {

                        //Command name

                        "copy": {

                            //Command handler

                            canExecute: copying,

                        }

                    }

                },

 
            });

  function copying(args) {            

            var node = args.model.selectedItems.children[0];

            if (node.branch == "root") {

                return false;

            }

            else

            {

                return true;

            }
        }
