The basic idea behind the Form Builder is simple - an online form is a number of components organized in a tree structure.

Each component has a set of properties:

  1. Different CSS styles for different screen resolutions.
  2. Simple properties (string, boolean, number, etc.).
  3. Events (onClick, onSelect, onClose, etc.).
  4. Actions are simply functions that are called when some event occurs.
  5. A set of rules for validating the value of a component.

Some component properties can be calculated using a JavaScript function or translated using the Fluent localization system.

Form Builder allows you to declaratively describe such components and then use them to create forms in the form designer.
