Crosslight Form Builder includes editor types that commonly used in mobile business apps, such as: button, checkbox, radio, password field, picker, date, time, etc. For more detail, kindly check the article, Supported Editor Types, in Crosslight Documentation which lists the editor types available in Crosslight.

Crosslight Form Builder also allows developer to use their own custom control in the form builder. The easiest way to implement your own custom editor is through the view resource. A view resource is comprised of a XIB file that represents the interface definition of the view, and a class that wraps the XIB file. The first step is specifying the custom control definition in the form metadata attribute, then create the counterpart in the iOS project. At runtime, Form Builder automatically resolve the specified custom editor and instantiate your class to be consumed in the generated form.

This section, Using Custom Editor, in Understanding iOS Form Builder article shows the steps to create a custom control that shows a map and a progress bar that appear in the middle of the data form.

You can try to run the Form Builder sample project and navigate to Editors > Image Picker. It represents an editable image view which provides user interface to capture photo from camera or choose from the existing photo albums.
Or navigate to Date or Time Picker which provides user interface that allows users to pick a date or time value - represented in a light modal.

Hope this helps.
