Admin Magento Category Tree

Question

How to show the category tree, which is located in the admin menu in the administration section somewhere on another page [but on the admin side].

Also I don't want to generate a tree using custom js. You just need to use the default functions.

Answer 1

$this->getLayout()->createBlock('adminhtml/catalog_product_edit_tab_categories')->setTemplate('catalog/product/edit/categories.phtml')->toHtml();
