Does the POWER theme support HubSpot's new multi-step forms?
At the moment HubSpot does not allow for third party styling or customisations on their new, multi-step forms tool.
The POWER theme supports HubSpot's original (now called legacy forms editor) as it allows for customisations using HubSpot's language Hubl and integration into a custom, third party module.
Currently HubSpot do not allow for any third party styling or functionality customisations to their new forms module, this includes the new multi-step forms functionality. Due to HubSpot not allowing for third party customisation on these forms we cannot currently add any of our POWER theme styles to this new form editor, and no theme provide can add their customisations to this tool.
We are working closely with HubSpot to try get this functionality available, once this is our team will work hard to make this available within our theme.
