Steps also known as Stepper, is an indicator for the steps in a workflow.
Steps requires a collection of menuitems as its model.
Steps can be controlled programmatically using activeStep property.
Steps is linear by default to enforce completion of a previus step to proceed, set readonly as false for non-linear mode.
Steps offers item customization with the item template that receives the item instance from the model as a parameter.
Steps component uses the nav element and since any attribute is passed to the root implicitly aria-labelledby or aria-label can be used to describe the component. Inside an ordered list is used where the current step item defines aria-current as "step".
