This example uses the Contact Form 7 Multi-Step Forms plugin and can be done in both the Free and Pro versions. It demonstrates how you can skip the first step and populate the second step with values from a URL. The forms use the default:get attribute found in the main Contact Form 7 plugin.
You can either fill out the form below or follow this link to jump to the second step with pre-filled values.
