Usage considerations

Saving and displaying values and placeholders

The component always saves an array regardless of how many selections have been made.
Any nulls in the array passed to selected documents or folders are not displayed.
Whether placeholder text clears on focus or input varies by device and browser.

Filtering and permissions

When the filter folder is used, the filtering folder itself is never suggested.
The user viewing the picker must have access to view documents and folders passed to the value. Only documents and folders 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.
