我正在使用我网站上的默认导航栏。我左边有4个li导航链接，右边有4个li。
我遇到的问题是当我调整窗口大小时，右侧导航链接会在折叠之前被推到左侧导航链接下。
我希望在将其推到左侧菜单链接下方之前将其折叠。
有谁知道我怎么能做到这一点？
任何帮助都会非常感激！
谢谢！

根据您提供的代码，您错过了（我认为）def parse(self, response):
sites = response.xpath('//div[contains(@class,"store_pricetable")]')
items = []
for site in sites:
item = mspItem()
item['model_name'] = response.xpath('//h2[contains(@class,"priceindia")]/text()').extract()
item['price'] = site.xpath('.//div[@class="store_price"]/text()').extract()
items.append(item)
return items
类的结束</div>标记以及结束container-fluid标记（除非您故意没有＆＃39;}添加这些？）
此外，您的HTML中也会显示此问题，这会导致显示问题：
</nav>然后在底部你关闭它：
<li>
<li class='dropdown'>
<a class='dropdown-toggle'....
您似乎只需要删除额外的 </ul>
</li>
</li>
和<li>。希望有所帮助。

最终问题是链接的标题太长，以至于当视口减少时，给定的空间根本无法容纳它们。
如果您查看我发布的示例，则会显示原始navbar，其中一个字体大小严重（不受欢迎，仅用于说明我的观点），另一个使用图标帮助解决问题。如果你将它打开成整页并开始减少它，你就会明白我的意思。
可能的解决方法：
@media (min-width: 768px) {
#test .navbar-nav li a {
font-size: 8px;
}
}
.divider {
margin: 75px 0;
border-bottom: 4px solid #f00;
