Groups in ComfyUI

ComfyUI groups are a UI feature not so much for "functionally bundling" nodes, but for handling nodes touching a frame (rectangle) together. Therefore, while convenient for visual organization, depending on placement, unintended nodes may move along with it.

If you want to create a functional unit, Subgraph is more suitable.

Creating a Group

Create Manually

  • Right click on canvas -> Add Group
  • Resize or move the frame to fit the nodes inside

Create from Selected Nodes

  • Select nodes -> Click # (Frame Nodes) in Node Selection Toolbox

Since the group frame is fixed as a rectangle, depending on the layout, unselected nodes may be included.
Since it reduces layout freedom, personally I don't use the group function much.

Editing Group Frame

Click the header of the group frame and operate from Node Selection Toolbox.

  • Color: Change color
  • Remove: Delete group frame

Operating Group

Right click the header of the group frame, or operate from ⋮ in Node Selection Toolbox.

  • Fit Group to Nodes: Automatically adjust frame size
  • Select Nodes: Select all nodes in the group
  • Bypass Group Nodes: Bypass nodes in the group all at once

Moving Group Frame

Dragging the group frame moves touching nodes together. When you want to fine-tune just the position, you don't want nodes to follow.

By dragging while holding Ctrl + Alt, you can move only the group frame.
