日主题美化-去掉分类category模块

CSF::createSection( $prefix, array(
            'title'  => '功能增强',
            'icon'   => 'fas fa-rocket',
            'fields' => array(
                 array(
                    'id'      => 'no_category',
                    'type'    => 'switcher',
                    'title'   => esc_html__( '去掉分类category', 'rizhuti-v2' ),
                    'desc'    => esc_html__( '启用后会去除掉分类目录的category（开启/关闭都需要保存一次固定链接方可生效）', 'rizhuti-v2' ),
                    'default' => true,
                ),
            )
        )
    );

随后把这行代码放在主题的functions.php文件最底部即可
