![](https://1449034948-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-L_NpOsk0sjotPXNy29Q%2Fuploads%2FStzFVl86oIDEj5oCoWPz%2Fsub-flowchart-node.svg?alt=media\&token=a68c93e3-3fe8-4a54-b3bf-b63c9044707d)

A sub-flowchart makes it possible to use a flowchart in a flowchart. When the sub-flowchart node in a flowchart is reached, the flowchart that is defined as sub-flowchart will start. Any flowchart can be used as a sub-flowchart. This allows you to create and use flowcharts as reusable functions that can be used in multiple other flowcharts.

When you drag and drop a flowchart node from the toolbar to the canvas, WEM shows a popup window that allowes you to select an existing flowchart to be added as a sub-flowchart. It is also possible to drag and drop a flowchart directly from the flowchart tab to the canvas.

### Properties

A sub-flowchart node has no properties. The property panel on the right does provide some information on the name of the flowchart and which exits it contains.

Sub-flowcharts can have multiple exits. Every End node in a (sub-)flowchart is also an exit of that (sub-)flowchart.
