FolderTree widget

The FolderTree widget allows creating a dynamic hierarchical tree structure with folders.

The main purpose of this widget is to represent a folder structure from the server, database or another resource and to allow the users to browse that structure.

The dynamic hierarchical allows us to easily update the folders via Ajax URL and show different levels of folders, with subfolders that can be collapsed and expanded.

For example: in the Wysiwyg editor, the FolderTree widget is used to represents the structure of media folders on the server. After clicking on one of the folders, an admin is able to see media files within the folder.

Example of Media Folder Tree

The FolderTree widget can be used only in the adminhtml area.

The FolderTree widget source is <Magento_Cms_module_dir>/view/adminhtml/web/js/folder-tree.js.

Initialize the FolderTree widget

For information about how to initialize a widget in a JS component or .phtml template, see the Initialize JavaScript topic.
