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

This article explains how to add a phase at runtime using the context menu in Vue Diagram. In Syncfusion® Vue 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, we demonstrate how to add a phase using the context menu:

contextMenuClick: (args) => {
 if ((args.item.id === 'InsertPhaseBefore' || args.item.id === 'InsertPhaseAfter') &&
       diagramInstance.selectedItems.nodes[0].isPhase) {
     // The currently selected phase
     let node = diagramInstance.selectedItems.nodes[0];
     let swimlane = diagramInstance.getObject(diagramInstance.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 a phase before the existing phase
     if (args.item.id === 'InsertPhaseBefore') {
       newPhase.offset = newPhase.offset - newPhase.offset / 2;
       diagramInstance.addPhases(swimlane, [newPhase]);
     } else {
       // To add a phase after the existing phase
       newPhase.offset = newPhase.offset + newPhase.offset / 2;
       if (newPhase.offset >= swimlane.width) {
         newPhase.offset = existingPhase.offset - 50;
       }
       diagramInstance.addPhases(swimlane, [newPhase]);
     }
     diagramInstance.clearSelection();
   }
 }
};
