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 Supplemental text about this field. Required required Boolean Determines if a value is required to submit the form. Default: false. Required Message requiredMessage Text Custom message to display when the field's value is required and not provided. Read-only readOnly Boolean Determines if the field should display as not editable. Default: false. Disabled disabled Boolean Determines if the field should display as potentially editable but grayed out. Default: false. Maximum Selections maxSelections Number (Integer) Maximum number of allowed selections. Once this number is reached, further selections are blocked until a selection is removed. Folder Filter folderFilter Folder When present, only documents that are inside this folder and its sub-folders are suggested. Display Value value List of Document Array of currently selected documents. Validations validations List of Text String Validation errors to display below the field when the value is not null. Validation Group validationGroup Text When present, the requiredness of the field is only evaluated when a button in the same validation group is pressed. The value for this parameter cannot contain spaces. For example, “validation group” is not a valid value. You need to add an underscore between words: “validation_group”. See the following recipes for more information: Configure Buttons with Conditional Requiredness Validation Groups for Buttons with Multiple Validation Rules' Save Input To saveInto List of Save One or more variables that are updated with the array of selected documents when the user selects or removes a document. Use a!save() to save a modified or alternative value to a variable. Placeholder placeholder Text Text to display in the field when it is empty. Does not show if the field is read only. 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". Accessibility Text accessibilityText Text Additional text to be announced by screen readers. Used only for accessibility; produces no visible change. 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. Usage considerations Saving and displaying values and placeholders Any nulls in the array passed into selected Documents are not displayed. The component always saves an array regardless of how many selections have been made. Whether placeholder text clears on focus or input varies by device and browser. Permissions and placeholders The user viewing the picker must have access to view documents passed to the value. Only documents that the viewing user has permissions to see appear in the suggestions list. When folderFilter is not null, the viewing user must have permission to view the filtering folder for any suggestions to be made.
