This is used to control whether specific field choices are hidden for a particular form

Usage

add_filter( 'frm_hide_field_choice', 'my_hide_field_choice', 10, 3 );

Parameters

• $should_hide (Bool)
• $choice_key (string)
• field (array|object)

Examples

Hide an option from the form.

To hide a specific option in a field, set the $choice_key to the option’s index.

The $choice_key uses zero-based indexing, meaning the first option is 0, the second is 1, and so on. For example, to hide the second option, set $choice_key to 1.

add_filter( 'frm_hide_field_choice', 'my_hide_field_choice', 11, 3 );
function my_hide_field_choice( $hide_field_choice, $choice_key, $field ) {
    if ( $field['id'] == 8 && $choice_key === 1 ) {
      return true;
    }
    return $hide_field_choice;
}

In the above code, replace 8 with the ID of your field and 1 with the index of your option.
