The stacked headers help you to group the logical columns in Kanban. It can be shown by setting ShowStackedHeader as true and by defining StackedHeaderRows.

Adding Stacked header columns

To stack columns in stacked header, you need to define KanbanStackedHeaderColumn property in StackedHeaderColumns with field names of visible columns.

The following code example describes the above behavior.

<ej:Kanban ID="Kanban" runat="server" KeyField="Status">
                    <ej:KanbanColumn HeaderText="Backlog" Key="Open" />
                    <ej:KanbanColumn HeaderText="In Progress" Key="InProgress" />
                    <ej:KanbanColumn HeaderText="Testing" Key="Testing" />
                    <ej:KanbanColumn HeaderText="Done" Key="Close" />
                            <ej:KanbanStackedHeaderColumn HeaderText="Unresolved" Column="Backlog,In Progress" />
                            <ej:KanbanStackedHeaderColumn HeaderText="Resolved" Column="Testing,Done" />
                <Fields Content="Summary" PrimaryKey="Id" Tag="Tags" />
List<Tasks> Task = new List<Tasks>();  
          protected void Page_Load(object sender, EventArgs e)

            this.Kanban.DataSource = Task;
           public class Tasks
              public Tasks()
              public Tasks(int Id, string Status, string Summary, string Type, string Priority, string Tags, double Estimate, string Assignee, string ImgUrl, int RankId)
                  this.Id = Id;

                  this.RankId = RankId;
              public int Id { get; set; }
