Hi @valdemaras!
Welcome to the FusionAuth Community!
I am not sure I understand your question fully. I believe you may be indicating you cannot get a new form to properly display? If this is the case, I would recommend that you review this video below which walks you through:
Creating a new form Adding custom fields Customizing the look of the new form by creating a new theme and customizing the messages and helpers within. Selecting your registration formRemember to select your form from within the Applications > Registration tab. I have filled in an example form for you.

Viewing the formTo view the newly created form, copy the registration URL as seen here:

Check out my highly modified form below. As mentioned in the video, I had to create a new theme to get this custom header text to show up under a Freemarker template (see below, regarding themes)

FusionAuth uses FreeMarker for its templating language.
A good understanding of this library/framework will be helpful if you are looking to customize the look and feel of a form. As mentioned in the video, you will want to create your own theme, and then select that theme under the tenant (tenants > general > theme) which houses your application.
ImportantThe default theme that ships with FusionAuth is 👉 read-only 👈 so another theme will need to be created if you want to modify how a form might appear.

I hope this helps!
