使用Element ui中el-select时，将显示的下拉框改为弹框_el-select弹出表格

代码如下：

        <el-form-item label="巡检人员" :label-width="formLabelWidth">
          <el-select
            v-model="addForm.inspectionPerson"
            placeholder="请选择巡检人员"
            ref="choose"
            multiple
            @focus="showSelectPersonDialog()"
          >
          </el-select>
        </el-form-item>
        <el-dialog :visible.sync="selectPersonDialogVisible" modal="false">
          <el-table
            :data="inspectionPersonList"
            @selection-change="handleSelectPersonList"
          >
            <el-table-column type="selection"></el-table-column>
            <el-table-column prop="name" label="姓名"></el-table-column>
            <el-table-column prop="age" label="年龄"></el-table-column>
            <el-table-column prop="gender" label="性别"></el-table-column>
          </el-table>
          <div slot="footer" class="dialog-footer">
            <el-button @click="selectPersonDialogVisible = false"
              >取 消</el-button
            >
            <el-button type="primary" @click="confirmSelectPerson"
              >确 定</el-button
            >
          </div>
        </el-dialog>

    showSelectPersonDialog() {
      this.$refs.choose.blur();
        this.selectPersonDialogVisible = true;
    },

为el-select绑定ref="choose"，在对应的方法里写入：this.$refs.choose.blur();这样下拉框就可以隐藏啦。
