Interface CellGroupIf

One node of a grouped header (AreaModelCellGroups): a group with children, or a leaf with a property (a leaf becomes a column).

Example

const groups: CellGroupIf[] = [
  { data: "Order", children: [{ data: "ID", property: "id" }, { data: "Date", property: "date" }] },
  { data: "Customer", toggle: true, children: [
    { data: "Customer", property: "customer", visibility: "always" },   // stays visible when collapsed
    { data: "City", property: "city" }] }
];
const columnDefs = CellgroupFactory.buildColumnDefs(CellgroupFactory.buildGroupExts(groups));
const header = new AreaModelCellGroups("header", groups, columnDefs, 34);
Copy
