# GroupStack

The GroupStack node is a SuperTool that creates a convenient interface for managing a list of nodes of the same type.

Within the GroupStack interface, you can create any number of nodes of the same type, and these nodes are linked together, providing a single output by connecting them one after the other in serial, in the order in which they appear in the stack. GroupStack is similar to GroupMerge, except with GroupMerge the nodes are merged together instead of creating a list of nodes where a 3D input is passed through.

This node is most often used to group nodes that have one input and modify the scene graph in some way. For example, the GroupStack node could be used to manage multiple CollectionCreate nodes, or multiple material edits.

Note: When the GroupStack node is first created, its type is not defined. You can create a node and then add it to the stacklist by Shift+middle-mouse and dragging from the Node Graph tab to the node's list in the Parameters tab. At that point, the GroupStack is permanently typed as a group of the type of node that was dragged in.
