Navigation Buttons¶

Navigation buttons open other menus. Use them to build hierarchies — a main menu that leads to specialized sub-menus.

PIE_CALL¶

Opens another Pie Menu when clicked.

Setup¶

Field	What to enter
Target Pie ID	The ID of the target pie (shown in its editor header)
Auto Open on Hover	Enable to open the sub-pie automatically when the mouse moves over this button

Example — Nested Pie System¶

Q → Main Pie
      ├── [Modeling] → PIE_CALL → Modeling Pie
      ├── [Sculpting] → PIE_CALL → Sculpt Pie
      └── [Animation] → PIE_CALL → Animation Pie

Auto Open on Hover

With this enabled, just moving toward the PIE_CALL button instantly opens the sub-pie. The transition feels seamless — no click needed.

MENU_CALL¶

Opens a Simple Menu when clicked.

Setup¶

Field	What to enter
Target Menu ID	The ID of the target Simple Menu

Use case¶

Put a large toolset in a Simple Menu, then access it from a Pie Menu button:

Main Pie  →  "All Tools" button (MENU_CALL)  →  Full Tool List (Simple Menu)

LAYOUT_CALL¶

Opens a Layout Menu when clicked.

Setup¶

Field	What to enter
Target Layout ID	The ID of the target Layout Menu

Use case¶

Main Pie  →  "Settings" button (LAYOUT_CALL)  →  Settings Panel (Layout Menu)

GPU_MENU¶

Opens a compact vertical dropdown list of sub-buttons when clicked — like a right-click context menu.

Setup¶

Add child buttons inside the GPU_MENU button. Each child becomes one item in the dropdown.

Use case¶

When you have a group of related actions that don't warrant a full sub-pie, but you still want them organized:

Pie Button: "Import"  →  GPU_MENU  →  FBX
                                   →  OBJ
                                   →  glTF

Info

GPU_MENU children support all the same button types — operator, property, etc.
