Is there a way to unselect the node? about angular-tree-control HOT 7 CLOSED

I'm also interested in a solution to this problem. I want a toggle behavior: click will select the node and clicking again unselects it.

I need to do this as well. How the heck do you clear a selected node?

I guess you need to change the following function in angular-tree-control.js in order to work for unselection condition.

$scope.selectNodeLabel = function( selectedNode ){
                        if (selectedNode[$scope.options.nodeChildren] && selectedNode[$scope.options.nodeChildren].length > 0 &&
                            !$scope.options.dirSelectable) {
                            this.selectNodeHead();
                        }
                        else {
                            if ($scope.selectedNode != selectedNode) {
                                $scope.selectedNode = selectedNode;
                                if ($scope.onSelection)
                                    $scope.onSelection({node: $scope.selectedNode});
                            }
                        // resetting the already selected node
                          else{
//selected-node="selectedNode" attribute is binded to
//$scope.selectedNode scope attribute in the directive so it needs to be clear in order to work.
                               $scope.selectedNode = {};
                               if($scope.onSelection)
            $scope.Onselection({node: $scope.selectedNode});
                         } 
                        }
                    };

Actually, what I want to do is unselect the currently selected node from within my controller. Any suggestions on how I could achieve that?

Further to this. I've tried setting selected-node to an empty object but it doesn't re-draw the tree and the node is still highlighted.

check the plunkr example for unselecting the selected node.

In my previous comment I typed the function name wrongly because of that it doesn't work now. I have corrected it. check the example. I have written few lines in angular-tree-control.js file as

 $scope.selectNodeLabel = function( selectedNode ){
                        if (selectedNode[$scope.options.nodeChildren] && selectedNode[$scope.options.nodeChildren].length > 0 &&
                            !$scope.options.dirSelectable) {
                            this.selectNodeHead();
                        }
                        else {
                            if ($scope.selectedNode != selectedNode) {
                                $scope.selectedNode = selectedNode;
                                if ($scope.onSelection)
                                    $scope.onSelection({node: selectedNode});
                            }
                            // resetting the already selected node
                            else{
                          //selected-node="selectedNode" attribute is binded to
                          //$scope.selectedNode scope attribute in the directive so it needs to be clear in order to work.
                            $scope.selectedNode = { "label" : "", "id" : "", "children": [] };
                            if($scope.onSelection)
                            $scope.onSelection({node: $scope.selectedNode});
                            }
                        }
                    };

Added a fix to the component based on @kadarbasha suggestion. A second click on a selected node will now unselect it.
