去掉上一节和下一节

修改 \course\format\ renderer.php

/**

     * Output the html for a single section page .

**/

注释掉如下：

// Title with section navigation links.
        $sectionnavlinks = $this->get_nav_links($course, $modinfo->get_section_info_all(), $displaysection);
        $sectiontitle = '';
        $sectiontitle .= html_writer::start_tag('div', array('class' => 'section-navigation navigationtitle'));
        $sectiontitle .= html_writer::tag('span', $sectionnavlinks['previous'], array('class' => 'mdl-left'));
        $sectiontitle .= html_writer::tag('span', $sectionnavlinks['next'], array('class' => 'mdl-right'));

同样注释掉这行，不然导航布局混乱

$sectiontitle .= html_writer::end_tag('div');
