Avoid using steppers to break up sections in a short form, or multiple times on one page.
Don’t.
Don’t embed steppers within steppers or use multiple steppers on one page.
Editable steps allow users to return later to edit a step. These are ideal for workflows that involve editing steps within a session.
Editable steps can be edited within a session.
Non-editable steps should be used when:
Non-editable steps cannot be edited once completed.
Mobile step text
Steps displayed at the top in text
Mobile step dots
Use dots when the number of steps isn’t large.
Mobile step progress bar
Use a progress bar when there are many steps, or if there are steps that need to be inserted during the process (based on responses to earlier steps).
Optional steps within a linear flow should be marked as optional.
Mark optional steps in linear flows as optional.
Optional steps
Horizontal steppers are ideal when the contents of one step depend on an earlier step.
Avoid using long step names in horizontal steppers.
On horizontal steppers, the step name and numbers appear on a horizontal bar, which can be fixed to the top of the page when scrolling down.
Vertical steppers are designed for narrow screen sizes. They are ideal for mobile.
Vertical steppers can be used in mobile as-is. Simply ensure that the contents for each step are responsive.
Linear steppers require users to complete one step in order to move on to the next.
Each linear step must be completed before proceeding to the next one.
Non-linear steppers allow users to enter a multi-step flow at any point.
Non-linear steps may be completed in any order.

Steppers may display a transient feedback message after a step is saved. Stepper feedback should only be used if there is a long latency between steps.
