Learn more about the Select parser
The select parser should be used to store recurring data. Unlike the input parser it stores values in the locator and references it inside a location.
If the host element has multi option set, you can pass multiple values to the parser and all values will be stored. By default only the first found value will be used.
All found values will be stored in the element settings inside the locator. New values will be added automatically by the parser and can be edit in the element settings.
