File preview UI elements offer various benefits such as conveying information, improving the aesthetic appeal of an interface, providing visual cues and feedback or presenting complex data or concepts in a more accessible way.

​
Configuring a File preview element

A File Preview element can be configured for both mobile and web applications.

​
File preview properties (web)

The settings for the File Preview element include the following properties:

  • Title: Specifies the title of the element. If the file is downloaded or shared, the file name should serve as the title used in the preview component.
  • Subtitle: Allows for the inclusion of a subtitle for the element.
  • Display mode: Depending on the selected display method, the following properties are available:

    • Inline → Has accordion:

      • false: Displays the preview inline without an expand/collapse option.
      • true (Default View: Collapsed): Displays the preview inline with an expand/collapse option, initially collapsed.
      • true (Default View: Expanded): Displays the preview inline with an expand/collapse option, initially expanded.

    • Modal → view icon is enabled

  • Has accordion: Introduces a Bootstrap accordion, facilitating the organization of content within collapsible items. It ensures that only one collapsed item is displayed at a time.
  • Source Type:
    • Media Library: Refers to PDF documents uploaded in the Media Library.

PDF documents uploaded to the Media Library must adhere to a maximum file size limit of 10 MB.

  • Process Data: Identifies the key location within the process where the document is sourced, establishing the linkage between the document and process data.
  • Static: Denotes the document’s URL, serving as a fixed reference point.

It’s worth noting that the inline modal view can raise accessibility issues if the file preview’s height exceeds the screen height.
