RockIt Multi-Step Form Builder lets you build multi-step forms visually:
Partial capture — most form plugins only save a submission once the visitor hits the final Submit button. This plugin saves progress automatically as visitors fill in each field, so even someone who fills in just their name and email before abandoning the form still shows up in your Leads dashboard, ready for follow-up.
Leads dashboard — see every submission (partial or complete) in one place, filter by form or status, view full field-level detail, and export to CSV.
