# Parent Component Object

**Parent Component Object** is always used in combination with a [Component Object](/nodes/component-utilities/component-object). A **Parent Component Object** will search upwards in the component tree until it finds a **Component Object** node and mirror that node. Any change being done to one node will be reflected in the other nodes. Multiple **Parent Component Object** nodes in the same component will always mirror the same **Component Object**.

</div>

The node is used much like an [Object](/nodes/data/object/object-node) where you can output properties on the node. The node does not have an **Id** instead the data is shared with the parent component. This node is very useful in patterns such as radio groups where child components may need to access the **Component Object** of its parent.

| <span className="ndl-data">Properties</span> | {/*##input:value-\*##*/}The properties to set on the closest parent [Component Object](/nodes/component-utilities/component-object). When this input is changed via a connection the parent **Component Object** will be updated.{/*##input##*/} |

| <span className="ndl-signal">Fetch</span> | {/*##input:fetch##*/}Normally when a **Parent Component State** is created, the property outputs are immediately updated. If you want to control how the data is updated you can connect to the _Fetch_ signal input. Then you need to explictly send a signal to fetch the data.{/*##input##*/}<br/><br/>With **Fetch** connected the output data won't change until **Fetch** is explicitly triggered again. |
