Overview
Documentation
The Form UI component allows you to visually represent and edit data stored in an object. The UI component binds each layout item to a specific field in an existing data object. To display a simple form, you can assign the required object to the formData property. With the Form UI component, you can specify the location of labels against corresponding editors and number of columns used in the form layout. Optionally, the component can determine the column count based on current form width (adaptive rendering).
Feel free to share demo-related thoughts here.
