How to Add Phase at Runtime Using Context-menu in Angular Diagram?

In this article, you can learn about how to add a phase at runtime using the context menu in Angular Diagram. In Syncfusion® Angular Diagram, you can dynamically add phases to a diagram at runtime using a context menu. This feature enhances user interaction by allowing users to insert phases directly into the swimlane.

To add phase using context menu, you can use addPhases method. In addPhases method, you pass the selected swimlane and new phase data as arguments

In the following code, demonstrates how to add phase using context menu:

public contextMenuClick(args: MenuEventArgs): void {
 if ((args.item.id === 'InsertPhaseBefore' || args.item.id === 'InsertPhaseAfter') &&
   (this.diagram.selectedItems.nodes[0] as any).isPhase) {
   // The currently selected phase
   let node = this.diagram.selectedItems.nodes[0];
   let swimlane = this.diagram.getObject((this.diagram.selectedItems.nodes[0] as any).parentId);
   let shape = (swimlane as any).shape;
   let existingPhase = shape.phases[node.columnIndex];
   // The currently selected phase
   let newPhase = {
     id: randomId(),
     offset: (existingPhase as any).offset,
     header: { style: (existingPhase as any).header.style },
     style: (existingPhase as any).style,
   };

   //To add phase before existing phase
   if (args.item.id === 'InsertPhaseBefore') {
     newPhase.offset = newPhase.offset - newPhase.offset / 2;
     (this.diagram as Diagram).addPhases(swimlane, [newPhase]);
   } 
   else {
     //To add phase after existing phase
     newPhase.offset = newPhase.offset + newPhase.offset / 2;
     if (newPhase.offset >= (swimlane as any).width) {
       newPhase.offset = (existingPhase as any).offset - 50;
     }
     (this.diagram as Diagram).addPhases(swimlane, [newPhase]);
   }
   this.diagram.clearSelection();
 }
}
