Selectable: false for Kanban Board groups

GoJS
1

Just a minor issue. In the Kanban Board Example selectable: false is missing for the groupTemplate. This leads to problems when trying to select all nodes using Ctrl + A.

Edit: To be more specific: When selecting all nodes using Ctrl + A and dragging them to another lane, nothing happens, because the groups are also included in the selection.

That’s a good point. We’ll update the sample. Thanks!

Actually, it’s a bit more complicated than that, because with your suggested change when the user has selected a few nodes and then clicks in a blank area in a lane/group, the selection is not cleared. Whereas if they clicked on the window background, the selection is cleared. I think most people would want a click on a group in that sample to clear the selection, so I have added a click handler on the group:

    myDiagram.groupTemplate =
      $(go.Group, "Vertical",
        {
          selectable: false,
          selectionObjectName: "SHAPE", // even though its not selectable, this is used in the layout
          layerName: "Background",  // all lanes are always behind all nodes and links
          layout: $(go.GridLayout, . . .
          click: function(e, grp) {  // allow simple click on group to clear selection
            if (!e.shift && !e.control && !e.meta) e.diagram.clearSelection();
          },
          . . .

Thank you, I can also use that in my adapted version of the Kanban Board!
