Context Menu button click issue

I am getting the context-menu successfully. When one of the context menu is clicked I need it to be appeared as the following screenshot:Capture1

Now I am getting it in the center of the “roundedrectangle” as shown in the following screenshot:

I am pasting the code below:

private prepareSubProcessGroupTemplate() {
const topBottomMargin = 5;
const rightLeftMargin = 5;
const noSize = new go.Size(NaN, NaN);
const minSize = new go.Size(1, 1);
return go.GraphObject.make(go.Group, ‘Spot’,
{
locationSpot: go.Spot.Center,
locationObjectName: ‘SHAPE’,//ToDo:for sub process locationObjectName was PH changed to SHAPE
// locationSpot: go.Spot.Center,
isSubGraphExpanded: false,
resizable: true, resizeObjectName: ‘SHAPE’,
memberValidation: (group: object, part: object) => {
return !(part instanceof go.Group) ||
(part.category !== ‘Pool’ && part.category !== ‘Lane’);
},
mouseDrop: (e: object, grp: go.Group) => {
const ok = grp.addMembers(grp.diagram.selection, true);
if (!ok) grp.diagram.currentTool.doCancel();
},
// context menu will be assigned form diagaram componet
// contextMenu: activityNodeMenu,
contextMenu: {},

    itemTemplate: this.boundaryEventItemTemplate
  },

I’m sorry, but you have commented out the original contextMenu and set it to an invalid object. Are you using go-debug.js and checking the console output for any warnings or errors?

And your code (which would be more readable if it were formatted correctly, Code Formatting) does not appear to implement a context menu at all. Perhaps it’s implemented elsewhere?

Didn’t get your point…Please explain me…Pasting the code again:

    const topBottomMargin = 5;
    const rightLeftMargin = 5;
    const noSize = new go.Size(NaN, NaN);
    const minSize = new go.Size(1, 1);

      {
        locationSpot: go.Spot.Center,
        locationObjectName: 'SHAPE',//ToDo:for sub process locationObjectName was PH changed to SHAPE
        // locationSpot: go.Spot.Center,
        isSubGraphExpanded: false,
        resizable: true, resizeObjectName: 'SHAPE',
        memberValidation: (group: object, part: object) => {
          return !(part instanceof go.Group) ||
            (part.category !== 'Pool' && part.category !== 'Lane');
        },
        mouseDrop: (e: object, grp: go.Group) => {
          const ok = grp.addMembers(grp.diagram.selection, true);
          if (!ok) grp.diagram.currentTool.doCancel();
        },
        // context menu will be assigned form diagaram componet
        // contextMenu: activityNodeMenu,
        contextMenu: {},

        )  // end Vertical Panel
      )
    );  // end Group
  } ```

I was just saying that I did not see the definition of your context menu. And I still don’t see it in the code that you just posted.
