The Container Web Control creates a container that can be used to segment or separate elements on a Web Page. Containers can be added to Web Pages or nested within many other Web Controls such as repeaters.
Roles provide a semantic association to a Container, allowing assistive technologies to interact with that Container according to users' expectations. The roles available for a Container are:
The aria-label attribute is used to define a string that labels the current element. It is used to provide an accessible name for the control. For more information see here.
Designates a dynamic Container to be recognized by assistive technologies. A dynamic Container is an element that do not require the whole Web Page to reload in order to change. Users may choose one the following ARIA Live properties:
- off: ARIA Live attribute is disabled.
- Polite: assistive technologies will notify users of updates when they are idle, without interrupting their current task.
- Assertive: any updates made to the Container are notified immediately.
The ARIA Atomic attribute allows you to define if assistive technologies will recognize changes to the selected Container. If
TRUE is selected, any dynamic change in the Container will be notified to the user. This property is
FALSE by default.
This attribute establishes if the Container will trigger notifications by assistive technologies when they are modified. Users may choose one of the following ARIA Relevant properties:
- additions: when text or content is added to the designated Container.
- removals: when text or content is deleted from the designated Container.
- text: when text is added inside the designated Container.
- all: All of the abovementioned actions:
TRUE the Container will be visible. If
FALSE the container will not be displayed. If the field is empty, the container will be visible.
TRUE, the Container will be disabled and the user will not be able to interact with the Control. If
FALSE, it will be enabled. If the field is empty, it will be enabled.
This provides the ability to distribute the elements evenly in the container, based off of the selected setting.
Distribution Box - Shows how children Controls are distributed by default and allows you to quickly change their position as a block within the Container.
Stack Horizontal - Aligns all children Web Controls horizontally.
Stack Vertical - Aligns all children Web Controls vertically.
Wrap - Specifies whether all children Web Controls should be wrapped inside the Parent or not.
Spacing Children - Configures how much space is taken around each child Web Control. Possible choices are to provide a Theme Variable, or an Airscript Expression. If providing an Airscript Expression, it must result in a string with a valid size.

The app builder may want to only display a set of elements if an app user has completed a previous field. Change the Is Visible property of the Container to evaluate to
