| Model ID             | The unique identifier of the element within the process model.                                                                                                                                                                                                                                                                                               |

| Documentation        | A description and any additional information about this element.                                                                                                                                                                                                                                                                                             |
| Condition expression | A conditional expression that must evaluate to `true` for the flow to be followed. All qualifying outgoing sequence flows are followed. Use any expression that evaluates to `true` or `false`, such as `${root.needApproval}` or `${nextStep == 'approved'}`. Conditions are ignored for sequence flows after a parallel gateway.                           |
| Skip expression      | <p>An expression that bypasses any condition if <code>true</code> and selects the flow.</p><div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>You must opt-in to enable this feature by setting a process variable <code>\_FLOWABLE\_SKIP\_EXPRESSION\_ENABLED</code> with the Boolean value <code>true</code>.</p></div> |
| Default flow         | Defines the sequence flow as a default.                                                                                                                                                                                                                                                                                                                      |

| Execution listeners | <p>Allows you to invoke Java logic after certain events:</p><ul><li><strong>Start</strong>: Executes after the activity has been started.</li><li><strong>End</strong>: Executes after the activity was completed.</li><li><strong>Transition</strong>: When defined on a sequence flow, executes once the flow is transition is taken.</li></ul> |
