Label Position

labelPosition

Text

Determines where the label appears. Valid values:

  • "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.

When present, this field is only validated when a button in the same validation group is pressed. See the documentation for more information about how to use validation groups.

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".

Boolean

Determines whether the component is displayed on the interface. When set to false, the component is hidden and is not evaluated. Default: true.

Accessibility Text

accessibilityText

Text

Additional text to be announced by screen readers. Used only for accessibility; produces no visible change.

Notes

  • If you set Label Position to "ADJACENT" or "ABOVE", but do not give a value for Label, a space still displays to the left-side or above, respectively, of the component as if there was a label displayed. To ensure the component appears to the far left when Label has no value, use "COLLAPSED" for Label Position.
  • If Read-only is set to true, the Display Value displays without a box around it.
  • If you pass the same local variable to Display Value and saveInto when Read-only is set to false, you can use the user's input into the component to modify the interface.
  • Whether placeholder text clears on focus or input varies by device and browser. Placeholder text does not display on Microsoft Internet Explorer 9.
