Please note, Multi Step Forms require intermediate Webflow experience in order to get the most out of customisation.
Our team is unable to provide customisation support when using the forms.
Forms are built using the native Webflow Slider Component, and contain a small bit of custom code that allows us to connect the slider next and back buttons. You can review the code from inside the embed element located within the forms layers.
Please ensure this code matches exactly your class names and that you are previewing a published site. (Custom code will not work with the designer preview).
