Locking TreeGrid Example

This example is an advanced tree example. It illustrates:

• Locked columns
• Multiple headers
• Preloading of nodes with a single AJAX request
• Header hiding, showing, reordering and resizing
• useArrows configuration
• Keyboard Navigation
• Discontiguous selection by holding the CTRL key
• Using custom iconCls
• Animation disabled because the right side is a normal grid (which does not animate record insertion).

Note that the js is not minified so it is readable. See locking-treegrid.js.
