Notes for Inserting a Child Step into a BRANCH Step
When you build a BRANCH step in the Layout tab, keep the following points in mind:
*You can insert a flow step as a child (target) of the BRANCH, or insert a flow step into an existing target.
*In the Layout tab, Designer evaluates the target steps of a BRANCH from top to bottom. At run time, Designer executes the first target with a matching switch value or an expression that evaluates to true.
*A target with the $default label will be evaluated last, regardless of its position.
*A target without the $default label has a dashed line at the bottom of the BRANCH to indicate the flow of execution.
