Dropdown By Index

Function: a!dropdownFieldByIndex()

Displays a limited set of exclusive choices from which the user must select one item and saves the index of the selected choice. To save a value instead of the index, use a dropdown. This component is not available from the interface component picker in the design view.

"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.

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.
• Choices display in the same order as defined in the Choice Labels parameter. The Choice Labels argument cannot be null.
• Passing a null value to the dropdown's Selected Index parameter causes the placeholder text to appear selected. The Placeholder Label and Selected Index arguments cannot both be null. If the placeholder is selected and Required is true when a validating button is clicked, the field prompts the user to select a value.
• The argument passed to the Placeholder Label parameter does not have an index.
• Choice index numbers start at 1. The index number for Selected Index cannot be null, empty, less than 1, or greater than the length of the Choice Labels array.
• The choice at the index passed to the Selected Index parameter displays as selected by default.
