How It Works
The plugin runs synchronization on every access to the frontend page of your website. Elements are located in the corresponding directories of the plugin's working directory — web_assets folder in the root directory of your website.
If you put file with element's content not to the it's base folder (chunks, templates, plugins and snippets folders respectively) this directories tree will be converted to element's categories tree.
E.g. chunk that is located in the file chunks/Frontend/Navigation/MainMenuItem.html will be displayed in manager panel as:
Note that MODx correctly works only with two levels of categories. That's why plugin will truncate longer caterory trees.
Special PHPDoc-like comments are supported for PHP files (snippets and plugins).
