Using [**Create a Hierarchy**](/docs/api/pxm/products/create-hierarchy), create a hierarchy whose name is **Major Appliances**. Each hierarchy has a hierarchy ID. In other words, the hierarchy ID is the ID of the root node.1. Using [**Create a Node in a hierarchy**](/docs/api/pxm/products/create-node), create the following child nodes. When you create a node in a hierarchy, by default, the node is a child of the root node. Specify `sort_order` to configure the order of the nodes. - **Ranges** - **Refrigerators** - **Dishwashers**1. Using [**Create a Node in a hierarchy**](/docs/api/pxm/products/create-node), create the **Electric Ranges** node, specifying **Ranges** as the parent node.1. Using [**Create a Node in a hierarchy**](/docs/api/pxm/products/create-node), create the following nodes, specifying **Electric Ranges** as the parent node. - **Electric Ranges 24ˮ** - **Electric Ranges 30ˮ** - **Double Oven**1. Using [**Create a Node in a hierarchy**](/docs/api/pxm/products/create-node), create the **Gas Ranges** node, specifying **Ranges** as the parent node.1. Using [**Create a Node in a hierarchy**](/docs/api/pxm/products/create-node), create the following nodes, specifying **Gas Ranges** as the parent node. - **Gas Ranges 24ˮ** - **Gas Ranges 30ˮ** - **Gas Ranges 32"** - **Double Oven**1. Using [**Create a Node in a hierarchy**](/docs/api/pxm/products/create-node), create the following nodes, specifying **Dishwashers** as the parent node. - **Built-in** - **Standalone**## Hierarchies and Catalogs```
