Project Collections Tree Structure
The Project Collections Tree displays project-wide collections, templates, and settings organized in the left panel "Collections" tab. Items in this tree are shared across all data in the project. This page documents all collection types in the exact order they appear, as defined in ProjectCollectionsBar::PopulateCollectionTree().
Collections Structure Table
The following table lists all collections in the Project Collections Tree in the exact order they appear. Click the links to access property documentation for each collection type.

Collections Table Notes
- All items are top-level collections in the Project Collections Tree
- Context Menu - Most items use default context menus (right-click for add/delete/rename)
- Properties - Properties shown when individual items within collections are selected
- Shared Data - All items in this tree are project-wide resources shared across all spatial data
- File Storage - HTML, PYTHON, and Recycle items are stored as files in the project directory
