- $args (array)
- limit (int) - the maximum number of options to include in the lookup field

Add extra content to lookup options
This example adds more content around the values shown in a lookup field. It changes the options like '2.1', '2.2' to 'Version 2.1 is updated', 'Version 2.2 is updated'.
add_filter( 'frm_filtered_lookup_options', 'change_lookup_options', 10, 2 );
function change_lookup_options( $options, $args ) {
if ( $args['field']->id == 25 ) { // change 25 to the id of the field in the other form
foreach ( $options as $k => $option ) {
$options[ $k ] = 'Version ' . $option . ' is updated';
}
}
return $options;
}
