I've got a page where a plugin seems to be overriding the z-index of my dropdown menu element in mobile. The dropdown is set to z-index: 100; and it works for all other pages, but on the one page I have a plugin, the plugin shows over the menu when it's dropped. Either the plugin z-index is set to 100, or it's overriding z-index of the dropdown menu.
因此，我找到了插件ID并将其作为目标，但没有用。
#wpcf7-f337-p187-o1 {z-index: 98;}
首先，我定位了容器元素，但没有用，然后是容器元素，接着是类，却没有用，然后像下面这样的特异性：
.entry-content>.wpcf7{z-index: 98;}
没工作
因此，我在该页面中将主体设置为z-index 98，但是没有用。
body.page-id-187{z-index: 98;}
没用
Both .dropdown-menu and the container .collapse are set to z-index 100, background-color: white like so:
@media(max-width: 768px){ul.dropdown-menu li a{position: relative; left: 55px; text-align: unset; font-size: 38px !important; background-color: white; color: black !important; line-height: 30px !important; padding: 0px !important; width: unset !important; margin-left: unset !important;z-index: 100;}}
所以：
@media(max-width: 768px){.collapse {position: absolute; height: 775px; background-color:white; z-index: 100; top:75px; left: -50px; line-height: 10px;}}
