This example demonstrates how to use conditional placeholders in the Sequential Workflow Designer Pro. The conditional
placeholders feature allows you to dynamically control which placeholder should be visible. In this example, you can place
"Blue" steps only inside the "Only Blue" steps. Similarly, you can place "Red" steps only inside the "Only Red" steps.
Additionally, in the root sequence, you cannot add any steps between existing steps; you can only add a new step at the end of
the sequence.
