无法处理下拉菜单中子类别的结论。只做了第二级（菜单 - >子菜单），但第三级和第四级立即出现。CSS菜单不显示子菜单
我有：类别1 - >类别2 - >类别3 - >类别4
当悬停在1类别我从所有其他类别都有。但应交替：在类制成1只有到类别 2只类别3

.submenu_3
%ul
- children_3.sort_by(&:name).each do |child_3|
= link_to "/catalogs/#{child_3.to_param}.html" do
%li= child_3.name如果我使用正确生成.menu ul li:hover > .submenu由第2类，但不显示在3或4菜单级别。
请帮助正确组织代码haml和css。如何组织.submenu_2和.submenu_3？
尽量提供编译的HTML。 –
