Which function is commonly used to create a read-only display of data in Appian?

The function a!richTextDisplayField() is designed to create a read-only display of text that can include rich formatting, such as different colors, fonts, and styles. This makes it particularly useful for presenting data in a structured and visually appealing way without allowing user input or editing.

In contexts where displaying dynamic information or static content is necessary, using a rich text display field enables developers to present information clearly while leveraging styling for emphasis. This is especially pertinent for user interfaces where the goal is to inform users without the need for modifications.

The other functions listed serve different purposes. For instance, a!displayText() allows for basic text display but does not support advanced formatting. a!textField() is specifically for capturing user input, making it unsuitable for a read-only context. Meanwhile, a!gridField() is used to display tabular data that may allow user interactions, such as selecting rows, which also does not align with the read-only objective. Thus, a!richTextDisplayField() stands out as the most appropriate choice for creating a read-only display of data.
