html - Angular 7+ : ngbDropdown menu collapse instead of popover

Question

我正在使用 ngb 下拉列表在屏幕上显示用户列表。当用户单击下拉菜单时，它会显示用户详细信息表单。

问题 是，此表单会在其他用户和内容之上弹出。我需要用户详细信息折叠而不是弹出。

我尝试设置 aria-haspopup=false 但这没有任何作用，事实上它在检查器中仍然显示为 true，所以我对它的作用以及现在如何实现这一点感到有点困惑？我正在考虑像在导航栏切换器中那样使用数据切换和折叠之类的东西，但不确定如何在 ngbDropdown 菜单中正确实现它....

<div ngbDropdown *ngFor="let user of users" class="user-list">
    <a ngbDropdownToggle id="dropdownForm" role="button" aria-haspopup="false" aria-expanded="false">{{user.firstName}} {{user.lastName }} </a>
    <div ngbDropdownMenu aria-labelledby="dropdownForm">
      <userForm></userForm>
    </div>
</div>

从您分享的描述/图片来看，您似乎需要 Accordion ，而不是弹出式...因为 Accordion 具有可折叠效果，而下拉菜单始终是弹出式

相关HTML:

<ngb-accordion #acc2="ngbAccordion" activeIds="ngb-panel-0" [closeOthers]="true">
  <ngb-panel  *ngFor="let user of users; let idx = index" class="user-list" >
    <ng-template ngbPanelTitle >
      <span  (click)='toggleAccordion(idx)'>{{user.firstName}} {{user.lastName }}</span>
      <span class='stickToRight' (click)='toggleAccordion(idx)' style='float:right'> 
        <!-- ... {{idx}} - {{user.opened }} -->
        <ng-container *ngIf="user.opened">
        <i class='fa fa-angle-down'></i>
        </ng-container>
        <ng-container *ngIf="!user.opened">
        <i class='fa fa-angle-right'></i>
        </ng-container>
      </span>
    </ng-template>
    <ng-template ngbPanelContent>
      <!-- <userForm></userForm> -->
      <input type='text' placeholder="first Name" value="{{user.firstName}}" />  <br/>
      <input type='text' placeholder="last Name" value="{{user.lastName}}" /> <br/>
      <input type='text' placeholder="Age" /> <br/>
    </ng-template>
  </ngb-panel>
</ngb-accordion>

相关TS:

import { Component } from '@angular/core';

@Component({
  selector: 'ngbd-accordion-basic',
  templateUrl: './accordion-basic.html',
  styles: [`
  .stickToRight{position: absolute; right: 30px;}
  `]
})
export class NgbdAccordionBasic {
  users = [
    { firstName: 'fName 1', lastName: 'lName 1', opened: false },
    { firstName: 'fName 2', lastName: 'lName 2', opened: false },
    { firstName: 'fName 3', lastName: 'lName 3', opened: false },
    { firstName: 'fName 4', lastName: 'lName 4', opened: false },
    { firstName: 'fName 5', lastName: 'lName 5', opened: false }
  ];

  resetOthers(index) {
    for (var i = 0; i < this.users.length; i++) {
      if (i !== index) {
        this.users[i].opened = false;
      }
    }
  }

  toggleAccordion(index) {
    if (this.users[index].opened == false) {
      this.users[index].opened = true;
      this.resetOthers(index);
    } else {
      this.users[index].opened = false;
      this.resetOthers(index);
    }
  }
}
