It’s a reusable LWC component wizard, which can hold any number of child LWC components irrespective of their design.
- Each step is a child component.
- The number of steps will be identified dynamically based on the child component’s markups.
- On click of ‘Back’ and ‘Next’, components will be shown/hidden.
- ‘Next’ and ‘Finish’ button will take care of validating the inner child components too.
