This extension implements basic client-server logic. When user changes the tree (creates a node, renames a node or drags and drops a node, the request is sent to the server to execute, save this change.

FileTreePanel is client-server application where client (browser) provides the user interface (UI) which displays the tree and context menu, handles drag & drop operations, etc. The filesystem that is displayed and managed by the UI is stored on a server.

This extension implements tree panel with checkboxes that allow selection of individual branches or leafs.
The checked nodes define a “value” of the tree that is returned as list of values separated by a configurable separator.

This is very simple extension that helps to create trees from static arrays.
It adds configuration property children to Ext.tree.TreePanel that accepts multilevel nested array with the definition of tree nodes.
