# Asset Hierarchy

Learn how to manage a hierarchical structure of assets within the collection.

Hierarchies allow you to create logical connections between different assets in the same collection.

This allows you to traverse through the collection and link assets together.

A hierarchy is set by defining a parent-child relationship tree.

## Adding to Hierarchy

To add a new child or parent to an asset, click the **+Add Child** or **+Add Parent** buttons.

You will then be prompted to select the asset to connect from your collection.&#x20;

{% hint style="warning" %}
Cyclical hierarchy structures are not supported. Adding relationships that would result in such a structure will be rejected.
{% endhint %}

## Removing from Hierarchy

To unlink a relationship, click the **X** button in the top right corner of the parent or child asset.
