Parameters

Name Keyword Type Description
Label label Text Optional text to display as the field label.
Label Position labelPosition Text Optional text to determine where the label appears. Valid values include
  • "ABOVE" (default) Displays the label above the component.
  • "ADJACENT" Displays the label to the left of the component.
  • "COLLAPSED" Hides the label. The label will still be read by screen readers; see accessibility considerations for more information.
  • "JUSTIFIED" Aligns the label alongside the component starting at the edge of the page.
Instructions instructions Text Optional text displayed beneath the image.
Help Tooltip helpTooltip Text Displays a help icon with the specified text as a tooltip. The tooltip displays a maximum of 500 characters. The help icon does not show when the label position is "COLLAPSED".
Images images Array of Images A list of images to display created with
Size size Text Optional text to control what size image displays. Valid values are "STANDARD" (default), "ICON", "THUMBNAIL", "SMALL", "MEDIUM", and "LARGE".
Alignment align Text Determines alignment of the image(s). Valid values are "START" (default), "CENTER", and "END".
Visibility showWhen Boolean Determines whether the component is displayed on the interface. When set to false, the component is hidden and is not evaluated. Default: true.

The maximum display dimensions for each Size are listed below:

  • "ICON": 20x20 pixels
  • "THUMBNAIL": 100x200 pixels
  • "SMALL": 100x200 pixels
  • "MEDIUM": 200x400 pixels
  • "LARGE": 400x600 pixels
  • "STANDARD": natural dimensions

Notes

  • Images are scaled down as necessary to fit the size limit, preserving their natural aspect ratio. Images will never be scaled up, so they'll display at their natural size if they are smaller than the configured size.
  • Images look best with the "ICON" size if they are 40 x 40 pixels and have a transparent background. This size is recommended to ensure high quality rendering on high pixel density devices (E.g., MacBook Pros with Retina displays and many smartphones).
  • If Size is set to "THUMBNAIL", images can be clicked to open slideshows. With this configuration, images cannot have links associated with them.
  • If Size is set to "STANDARD", images display at either their natural width or the width of the column, whichever is smaller.
  • Avoid using this component for offline mobile forms because images do not render when offline.
