User Interface - Custom Visual Components

Introduction

Custom reusable Visual Components can be created in a project.

Custom Visual Components can be edited the same way as a screen (using UI Editor). custom_component_edit

The custom UI Components is then available in UI Editor Marketplace when editing Screens or other custom Visual Components.

Custom Properties

The property can be added in “Spec & doc” tab while editing the custom Visual Component.
