NestedSet Model for Navigation

model scheme

enhanced nested set model class

enhanced module action class

navigation list tabular cell template

Features:

• multiple roots
• move branch to another root
• copy branch with all subnodes
• sort nodes
• move to parent branch either to first or last child
• insert as first child, insert as last child
• delete operations
• etc.
