Building a Product Configurator: Tips & Best Options

Hi! Have anyone built a product configurator (similar to Tesla) with multi-step form? Would it be a good option to use Formly + Relume components (e.g. Multi Form 32) for this? I would like the image to change based on options you select + what question you’re answering. Also, if we ask for email in the first step, is there a way to save and send the email address if the user does not complete the form?
