Nested Screen Control
Add a Nested Screen control into which select a separate Screen that is in your ProcessMaker Platform instance.
Control Description
Use the Nested Screen control to nest a separate Screen into that control. In doing so, the separate Screen embeds into the Nested Screen control. The Nested Screen control is a placeholder for the embedded Screen such that the Request participant experiences the nested Screen as designed. When the Task loads the Screen using a Nested Screen control, the Nested Screen loads the latest version of the referenced Screen.
The Screen containing the Nested Screen control is the parent Screen. The Screen that is nested is the child Screen.
During an in-progress Requests, both Request and Magic Variable data pass to a child Screen when it displays within the parent Screen. Furthermore, information that is entered into a child Screen displays in Request summaries that use the parent Screen.
A nested Screen has the following attributes that vary from how it may have been designed:
CSS takes precedent: Any CSS designed in Custom CSS mode in the parent Screen takes precedent over any CSS designed in the child (nested) Screens. The Request participant experiences one design experience without a variety of design styles.
Submit Button control in nested Screens is hidden: During in-progress Requests, the Submit Button control is hidden in child Screens so that the Request participant uses the parent Screen's Submit Button control to submit the Task.
Two Screens cannot reference each other indefinitely: A child Screen that has already displayed within a parent Screen cannot display again in the same Request. This prevents an infinite loop whereby two Screens using Nested Screen controls reference each other indefinitely.
Only Display- and Form-type Screens may be selected for nesting into a Nested Screen control.
Screen designers can easily build a Screen by placing modular components into one Screen. For example, in a Screen designed for a purchase request, use Nested Screen controls as placeholders for the following components that are designed in separate Screens. Each of these Screens are nested into its own Nested Screen control.
Nested Screen control for Screen 1: Personal information
Nested Screen control for Screen 2: Payment information
Nested Screen control for Screen 3: Billing information
Nested Screen control for Screen 4: Shipping information
This control is only available for Form-type Screens. See Screen Types.
