如果要将这段代码改为多选，你需要在弹出框中添加复选框或多选框，并将选择的值存储在一个数组中。例如，你可以将变量`current`改为`selected`，并将其初始化为空数组`[]`。然后，将选中的值添加到`selected`数组中，而不是将其赋值给`current`变量。最后，在 `if` 语句中使用 `includes()` 函数来判断选中的值是否在相应的列表中。

以下是修改后的代码示例：

// 初始化为一个空数组
selected: [],

// 处理选择事件
handleSelect(value) {
  // 判断当前值是否已经选中，如果没有则添加到 selected 数组中
  if (!this.selected.includes(value)) {
    this.selected.push(value);
  }
},

// 处理搜索事件
handleSearch() {
  let area = this.arealist.filter(v => this.selected.includes(v.areaNo));
  console.log(area);
  let single = this.singlelist.filter(v => this.selected.includes(v.singleNo));
  console.log(single);
  let work = this.workingProcedureList.filter(v => this.selected.includes(v.procedureNo));
  console.log(work);
  let team = this.teamlist.filter(v => this.selected.includes(v.teamNo));
  console.log(team);
  let line = this.productLineList.filter(v => this.selected.includes(v.productLineNo));
  console.log(line);
  let project = this.projectlist.filter(v => this.selected.includes(v.projectNo));
  console.log(project);
  // ...
}
