Data structure:

  • Object Array
  • Object has to contain name:String and children:[another similar object] or children:null (with no children)
  • Object item can contain ..., icon: 'home' }, it can change a file icon
  • Object item can contain ..., classname: 'css_custom_class' }, it adds a CSS class onto "label" element

Methods:

  • component.expand([index]) - expands index or all (with no defined index) nodes
  • component.collapse([index]) - collapses index or all (with no defined index) nodes
  • component.clear() - clears a cache for refreshing source
  • component.select(index) - selects node
  • component.unselect() - unselects node
  • component.rename(index) - shows input for name renaming (it works with config.rename)

Good to know:

Setter automatically extends each object by adding .$pointer property with a tree index.
