# Expand Instance Node

The Expand Instance Node function can be activated by clicking the left mouse button just outside a collapsed instance node. The active region surrounding a collapsed instance node is indicated by the special cursor image shown in Figure 1.

The Expand Instance Node function expands an instance node so that the interface nodes of the network instance that the instance node represents become visible and the size of the instance node is increased. An instance node must be expanded to create binding links to the input nodes of the instance node and to create ordinary (causal) links from its output nodes. You can also expand all instance nodes in one operation.

Please note that links to and from an instance node can only be selected when the node is expanded.
