In this section, you learn all about the Form Builder theme and its basic concepts. You get all the knowledge needed to create your own theme.

When you're creating forms in the Form Builder, you have the option to preview forms right there inside the same interface.

How the form looks visually is controlled via the form layout that is selected for that form. This is defined inside the form settings as shown below:

Similar to how the layouts for pages work, the form layouts control how that form renders. This includes all elements as inputs, dropdown, submit button, and the success message.

The default theme includes a single form layout which should fit most use-cases. If you wish to do any visual tweaks, it's best to just modify the stylesheets.

For more advance case you might want to create a custom form layout. The best approach would be to copy the existing one and update the things you need to adapt. There are comments inside the default form layout that helps you find your way around.

Registering a Theme#

The default Form Builder theme is located at apps/theme/formBuilder/index.ts with the following content:

import DefaultFormLayout from "./layouts/DefaultFormLayout";
export default [
name: "form-layout-default",
type: "form-layout",
layout: {
name: "default",
title: "Default layout",
component: DefaultFormLayout

The default theme comes with a single form layout. To learn more about form layouts proceed to the next page.
