    I need to add a class to the dropdown topic select_class.
    the original function is:

    function bbp_get_form_topic_status_dropdown( $args = array() ) {

        // Parse arguments against default values
        $r = bbp_parse_args( $args, array(
            'select_id'    => 'bbp_topic_status',
            'select_class' => 'bbp_dropdown',
            'tab'          => false,
            'topic_id'     => 0,
            'selected'     => false
        ), 'topic_open_close_select' );

        // Filter & return
        return apply_filters( 'bbp_get_form_topic_status_dropdown', ob_get_clean(), $r, $args );
    }

    I tired to use this but didnt work

    function custom_callback($args = array() ) {
    
        $r = bbp_parse_args( $args, array(
            
            'select_class' => 'my-class',
            
        ) );
        
        return  $r;

}
add_filter( 'bbp_get_form_topic_status_dropdown', 'custom_callback', 12, 2);

    the ‘,2’ might be the issue, as you only then use 1, but try this

    function custom_callback($args) {
    
        $args['select_class'] = 'my-class' ;
            
       return  $args;

}
add_filter( 'bbp_get_form_topic_status_dropdown', 'custom_callback');

    I got Uncaught TypeError: Cannot access offset of type string on string

    ok, let’s just redo the whole thing

    function custom_callback( $args=array()) {

        // Parse arguments against default values
        $r = bbp_parse_args( $args, array(
            'select_id'    => 'bbp_topic_status',
            'select_class' => 'my-class',
            'tab'          => false,
            'topic_id'     => 0,
            'selected'     => false
        ), 'topic_open_close_select' );

        // Filter & return
        return apply_filters( 'custom_callback', ob_get_clean(), $r, $args );
    }
	

add_filter( 'bbp_get_form_topic_status_dropdown', 'custom_callback');
