</style>
<script>
export default {
name: 'Root',
data() {
return {
isCollapse: true
}
},
methods: {
handleOpen(key, keyPath) {
console.log(key, keyPath)
},
handleClose(key, keyPath) {
console.log(key, keyPath)
}
}
}
</script>
主要的写法就是
<template slot="title"> <i class="el-icon-location" /> <span slot="title">导航一</span> </template>
template 里面要有两个标签，一个是写img 或、这i图标的，但是还有一个救生衣写文字的。
通过collapse 去控制
