How to Add Phase at Runtime using Context-menu in React Diagram?

This article explains how to add a phase at runtime using the context menu in React Diagram. In Syncfusion® React 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 a phase using the context menu, you can use the addPhases method. In the addPhases method, you pass the selected swimlane and new phase data as arguments.

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

function contextMenuClick(args) {
 diagram = diagramInstance;
 if ((args.item.id === 'InsertPhaseBefore' || args.item.id === 'InsertPhaseAfter') &&
   diagram.selectedItems.nodes[0].isPhase) {
   // The currently selected phase
   let node = diagram.selectedItems.nodes[0];
   let swimlane = diagram.getObject(diagram.selectedItems.nodes[0].parentId);
   let shape = swimlane.shape;
   let existingPhase = shape.phases[node.columnIndex];
   // Create a new phase object to be added
   let newPhase = {
     id: randomId(),
     offset: existingPhase.offset,
     header: {
       style: existingPhase.header.style,
     },
     style: existingPhase.style,
   };
   //To add phase before existing phase
   if (args.item.id === 'InsertPhaseBefore') {
     newPhase.offset = newPhase.offset - newPhase.offset / 2;
     diagram.addPhases(swimlane, [newPhase]);
   } else {
     //To add phase after existing phase
     newPhase.offset = newPhase.offset + newPhase.offset / 2;
     if (newPhase.offset >= swimlane.width) {
       newPhase.offset = existingPhase.offset - 50;
     }
     diagram.addPhases(swimlane, [newPhase]);
   }
   diagram.clearSelection();
 }
}
