# 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.
