el-dropdown(下拉菜单)的入门学习
适用场景
el-dropdown和el-select的展示效果很相似，我暂时还未找到el-dropdown适合的使用场景
知识点
el-dropdown嵌套el-dropdown-menu，el-dropdown-menu嵌套el-dropdown-item使用- 下拉可设置成文本+图标，按钮+图标，统一在
el-dropdown的标签包裹位置设置 - 按钮+分割线+图标的设置通过
el-dropdown中的split-button和type属性控制，@click事件点击按钮文本触发 el-dropdown的trigger默认为hover，可以设置为clickel-dropdown的hide-on-click默认为true，即下拉菜单选项被选中后，会自动关闭下拉菜单，设置为false，不会自动关闭size可以控制下拉菜单的大小el-dropdown-menu需要指定slot为dropdownel-dropdown-item设置icon,左侧显示图标el-dropdown-item设置command对应el-dropdown的@command的参数el-dropdown-item设置divided 可以在菜单选项上方显示分割线el-dropdown和el-dropdown-item设置disabled,即不可选中
