问题:vue项目中使用了element-ui的Dropdown下拉菜单el-dropdown,想要修改其默认样式。
分析:el-dropdown下拉菜单渲染后的组件元素中包含有el-popover,此处需要尤其注意。
实现:
*
给el-dropdown-menu添加自定义class名dropdownMenu:
<el-dropdown-menu class="dropdownMenu" slot="dropdown"> <el-dropdown-item
command="menu1">菜单1</el-dropdown-item> </el-dropdown-menu>
*
样式写到style标签,不能使用scope,并且同时使用el-popover和自定义class名dropdownMenu:
<style lang="scss"> .el-popper.dropdownMenu { background-color: red; // 背景颜色
border: 1px solid #fff; .el-dropdown-menu__item { // 下拉菜单文字颜色 color: #fff
!important; } .popper__arrow::after { border-bottom-color: #0f93ee !important;
border-top-color: #0f93ee !important; }
.el-dropdown-menu__item:not(.is-disabled):hover { background: #40a8ee
!important; } } </style>
