Controls Use control rules to determine the appearance of a single property, such as a button or drop-down field, on a form. Standard controls As you build forms, use standard controls to bring consistency and predictability to the look and feel of your application. Use the Records Explorer to see a complete list of the standard controls available to you. Creating a custom control If no predefined control meets the needs of your application, you can create one. Control form - Completing the Control tab Pega Platform includes a set of standard auto-generated controls. As a best practice, use these controls to save development time and ensure consistency. By default, this tab is displayed when you open an auto-generated control or open a New rule. Control form - Completing the HTML tab For non-auto-generated controls, you can enter HTML source directly into the HTML Source text box. Control form - Completing the Pages & Classes tab Identify what is known about the class of each page that is referenced in the source HTML on the HTML tab. Control form - Actions tab Action sets determine the behavior of a control.
