In below code we have a line if ( empty( $groupTitles ) ) here we are checking if we have empty group title then performance-data__actions will work else dropdown-container will work so we have javascript code that take performance-data__actions and performance-data__select in javascript so make same changes for dropdown conatiner that takes values from dropdown-group and dropdown-option in javascript so that dropdown condition works smootly.
