I want to be able to check a checkbox that will select all available options within the SELECT_MULTIPLE dropdown element during configuration of my looker studio connector.
Is it possible with the current Looker Studio connector API. Default behavior is as in the picture: enter image description here
But I have seen one connector with a select all checkbox in the search bar. Using this reference: https://developers.google.com/looker-studio/connector/reference#legacy_1
