Provides powerful menu editor to replace category based menus in Magento 2.

List of menus is located in Admin Panel under Content > Elements > Menus.

Following is example how to replace main menu with user defined menu (with identifier main).

<referenceBlock name="catalog.topnav" remove="true"/>
<referenceBlock name="store.menu">
  <block name="main.menu" class="Snowdog\Menu\Block\Menu" template="Snowdog_Menu::menu.phtml">
     <arguments>
        <argument name="menu" xsi:type="string">main</argument>
     </arguments>
  </block>
</referenceBlock>

To add new type node You have to add new backend block that also implements \Snowdog\Menu\Api\NodeTypeInterface.

Backend block will be directly injected into menu editor. Note that only one instance of block will be rendered and You should handle showing and hiding of this block in javascript depending on selected type of node. (See view/adminhtml/web/js/category.js and view/adminhtml/templates/menu/node_type/category.phtml for reference)

Newly created block with additional method should be added via di.xml defining block instance and node type code (code will be stored in database).
