Problem with positioning title at the bottom of a layout

Hi, I have a question about a layout.I have a group with your title and under it, a series of nodes. My idea is to position the nodes first and the title at the bottom. I have been modifying the GridLayout of the group and the alignment of the internal panel but it doesn’t work, any idea? Thanks in advance.

      $(go.Group, "Auto",
                wrappingColumn: 2, alignment: go.GridLayout.Position,
                cellSize: new go.Size(1, 1), spacing: new go.Size(8, 8)
        new go.Binding("background", "isHighlighted", function(h) { return h ? "rgba(255,0,0,0.2)" : "transparent"; }).ofObject(),
        $(go.Shape, "RoundedRectangle", 
          new go.Binding("stroke", "stroke"),
          new go.Binding("fill", "background"),
          { strokeWidth: 1, parameter1: 10, alignment: go.Spot.Center}),
        $(go.Panel, "Vertical",
          $(go.Panel, "Vertical",
            { stretch: go.GraphObject.Horizontal},
            new go.Binding("width", "width"),
            new go.Binding("height", "height"),
                alignment: go.Spot.TopCenter,
                editable: false,
                margin: 5,
              new go.Binding("font", "font"),
              new go.Binding("stroke", "textColor"),
              new go.Binding("text", "text").makeTwoWay()), 
            { padding: 5, alignment: go.Spot.BottomCenter }),

You need to position the TextBlock so that it is below the Placeholder. There are lots of ways of doing that, depending on the visual appearance you want to give.

See for example

Great, changing the position of the Placeholder worked. It looks like it needed to. Thank you, Walter.
