# How to create Nested Array (Multidimensional Array)?

Nested Array is a wide-spread method to iterate an array inside another array. If you want to create a nested array you need to place a Container Component (or Table Component) inside another Container Component where one of them would have data field of the main array and the one inside would have nested array data.

**The Outer Array (Container Component)**
In this case The Outer Array represents different Orders and it is necessary to set the Container's data field to Orders (type Array).

**The Inner Array (Table Component)**

The Inner Array represents different Line_Items in corresponding Orders. In this case we have used a Table Component to represent the Inner Array. (it is possible to use a Container Component as well). It is also necessary to set the Table's data fields to Line_Items as you can see in the picture.

**Preview**

As you can see in the preview there were generated two different orders with corresponding line_items listed in the Table Component.

```
{
  "ORDERS": [
    {
      "OrderNumber": "ORDER #1",
      "LINE_ITEMS": [
        {
