【无标题】element select下拉框下拉选项位置不对，显示到旁边，不显示到下拉框底部

磁贴是用iframe引用，下拉框高度过长导致不显示在下面，修改下拉选项的高度

<el-select
        popper-class="custom-drop-select-item minePressure"
        class="custom-drop-select"
        v-model="state.selectIndex"
        filterable
        @visible-change="changeVisible"
      >
        <el-option
          v-for="(item, index) in state.selectList"
          :label="item.workingFaceName"
          :value="item.workingFaceNo"
          :key="index"
        ></el-option>
      </el-select>
.custom-drop-select-item.minePressure {
  .el-select-dropdown__wrap {
    max-height: 150px;
  }
}
