Implementing Syncfusion Vue TreeGrid

The Syncfusion Vue TreeGrid is a powerful data visualization component for displaying hierarchical data in a tree-like structure with grid functionality. It provides features for sorting, filtering, editing, exporting, and advanced data management.

⚠️ Security & Trust Boundary

• The TreeGrid skill does not perform any remote data access.
• All external API interaction is handled by a separate DataManager skill outside this skill’s trust boundary.
