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.
Examples application from my old website. The code of examples was written in/for ExtJS 3.x therefore it won’t work without modifications in Ext 4.x. However, the principles and coding practices can still be very useful.
These are examples, extensions and plugins written for ExtJS version 3.x so you cannot expect that they are going to work in the contemporary version of Ext. Still, coding practices, theory and principles may be valuable.
