The loop node makes it possible to loop through all the rows in a list or a multi-select field. When a loop node is dragged onto the canvas, a popup appears where you can select the list or multi-select field over which we need to loop.

When the node is selected the following properties can be specified:

You can do this by clicking the <code>Edit order</code>’ button that appears when this action is selected. From here you can specify an expression and specify the order (ascending or descending).</td><td></td></tr></tbody></table>

A loop node has two different exits:

* Next row

  When a new row has been reached, the node exits with the `Next row` exit. In the flowchart the user has to make sure to return to the loop node, in order to loop over the remaining rows.
* End of loop

  When all rows have been looped over, the node exits with the `End of loop` exit.
