  • When a user types in the picker's text box, the text they type is passed to the Suggestion Function. The returned DataSubset must have a Text array as data. Each item in that array is a selectable suggestion in the pane. If a suggestion is picked, the component's value is updated with the object at the same index of the DataSubset's identifiers array (in addition to any existing selected identifiers).
  • Selected Labels, Selected Values, Selected Links, and Selected Tooltips must all be the same length.
  • Whether placeholder text clears on focus or input varies by device and browser.
