• checked {String} optional, a path to function(arr, component) or path to property
• checkednested {Boolean} optional, checks all nested items (default: true)
• upload {String} optional, a path to function(item, files) (enables drag & drop files)
• dragdrop {String} optional, a path to function(item, target_item, itemel, targetel) (enables drag & drop items)
• options {String} optional, a path to function(item, el) enables a small button for an inline context menu for each item
• rename {String} optional, a path to function(item, newname, fn_accept(true))
• unselectexpand {Boolean} optional, can unselect selected item when the user clicks on the expandable item (default: false)

• expanded {Boolean} expands all children (default: false)
• NEW: contextmenu {String} optional, a path to function(item, el) enables mouse contextmenu
• NEW: key {String} a value can be used as index in below methods (default: path)

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 the "label" element
• Object item can contain ..., html: 'RAW_HTML' {String} renders HTML tags instead of name field

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 the 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.
