如何在div而不是window中打开Element-ui抽屉

如何解决如何在div而不是window中打开Element-ui抽屉

相对于使用完整的可用窗口，我试图在div中弹出一个抽屉。

var Main = {
    data() {
      return {
        drawer: false,direction: 'rtl',};
    }
  };
var Ctor = Vue.extend(Main)
new Ctor().$mount('#app')

@import url("//unpkg.com/element-ui@2.13.2/lib/theme-chalk/index.css");

.drawer-container{
  height: 600px;
  width: 600px;
  border: 1px solid red;
}
.drawer{
  height: 100%;
}

<script src="//unpkg.com/vue/dist/vue.js"></script>
<script src="//unpkg.com/element-ui@2.13.2/lib/index.js"></script>
<div id="app">
<el-radio-group v-model="direction">
  <el-radio label="ltr">left to right</el-radio>
  <el-radio label="rtl">right to left</el-radio>
  <el-radio label="ttb">top to bottom</el-radio>
  <el-radio label="btt">bottom to top</el-radio>
</el-radio-group>

<el-button @click="drawer = true" type="primary" style="margin-left: 16px;">
  open
</el-button>
<div class="drawer-container">
  <el-drawer
    class="drawer"
    title="I am the title"
    :visible.sync="drawer"
    :direction="direction">
    <span>Hi,there!</span>
  </el-drawer>
  </div>
</div>

我的问题是抽屉似乎完全忽略了父母css是什么。有谁知道改变这种状况的方法？

解决方法

事实证明，这就像添加position: relative

一样简单

var Main = {
    data() {
      return {
        drawer: false,direction: 'rtl',};
    }
  };
var Ctor = Vue.extend(Main)
new Ctor().$mount('#app')

@import url("//unpkg.com/element-ui@2.13.2/lib/theme-chalk/index.css");

.drawer-container{
  height: 600px;
  width: 600px;
  border: 1px solid red;
}
.drawer{
  position: relative;
  height: 100%;
}

<script src="//unpkg.com/vue/dist/vue.js"></script>
<script src="//unpkg.com/element-ui@2.13.2/lib/index.js"></script>
<div id="app">
<el-radio-group v-model="direction">
  <el-radio label="ltr">left to right</el-radio>
  <el-radio label="rtl">right to left</el-radio>
  <el-radio label="ttb">top to bottom</el-radio>
  <el-radio label="btt">bottom to top</el-radio>
</el-radio-group>

<el-button @click="drawer = true" type="primary" style="margin-left: 16px;">
  open
</el-button>
<div class="drawer-container">
  <el-drawer
    class="drawer"
    title="I am the title"
    :visible.sync="drawer"
    :direction="direction">
    <span>Hi,there!</span>
  </el-drawer>
  </div>
</div>
