Unlimited number of levels
COOLjsTree and COOLjsTree Professional support unlimited number of levels. No special
actions should be taken in case of big number of levels, just nest the
nodes:
var TREE1_NODES = [
['Item 1', null, null,
['Level 2', null, null,
['Level 3', null, null,
['Level 4', null, null,
['Level 5', null, null,
...
Don't forget that different levels can have different styles (see example) and different images (in Professional version, see example).
