# Designer

In this section, you can create a category tree. To do so drag a category from the left panel to the designer field. You must [create categories](/product-design/categories/create-a-new-category.md) before creating a tree structure.

{% hint style="info" %}
The system allows you to create a branch structure with up to 10 levels of depth.
{% endhint %}

An alternative way to create a category is to click on the *green plus icon* in the category panel. The process is the same as traditional [category creation](/product-design/categories/create-a-new-category.md).

You may move items in the tree simply by dragging them.

If you run out of space, simply click on *+ Add 10 rows.* Rows will be added at the bottom of a designer field.

To delete a category from a tree, drag it back to the Categories panel or click on the *kebab menu* and choose *Remove*.

To completely delete a category tree, click on *REMOVE CATEGORY TREE* in the top right corner.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://usermanual.ergonode.com/product-design/category-trees/designer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
