# Navigation sidebar

When **Show navigation sidebar** is enabled, a table-of-contents-style panel appears on the left side of the flow. This sidebar displays step groups and completed steps, allowing responders to easily navigate backward through the flow.

#### Access to future steps

* **Allow access to future steps** → Enables navigation to steps the responder has not logically reached yet.
* **Show disabled steps as read-only** → Displays future steps without allowing input until their logic is valid. This lets responders preview the flow without prematurely submitting data.
