Which layout is NOT suitable for presenting a dynamic container?

The choice indicating custom frames as unsuitable for presenting a dynamic container is based on how different layouts handle responsive design and dynamic content. Dynamic containers are specifically designed to adapt and change based on user interactions, such as showing or hiding content without needing to reload the entire page.

Custom frames, while versatile, are typically static in nature. They do not provide the inherent flexibility required for dynamically displaying content that changes in response to user actions or conditions. In contrast, dynamic layouts and tabbed layouts are engineered to support these adaptive functionalities effectively. Dynamic layout, for instance, automatically adjusts its contents and presentation based on the current context, making it ideal for dynamic containers. Tabbed layouts also facilitate the display of content in a manner that can change dynamically, enabling different sets of information to be shown based on user selection.

In contrast, placing a dynamic container outside any existing layout is generally avoided as it may not take advantage of the layout functionalities provided by Pega's UI framework. Such placements can lead to less controlled and predictable rendering, which undermines the benefits of having a dynamic container designed to interact smoothly within a structured layout.
