我正在尝试创建一个mat-nav-list,其中mat-expansion-panels作为列表项。问题是,mat-nav-list无法按预期工作。对齐很乱,扩展面板无法正常工作。我认为,这是因为mat-nav-lists不支持mat-expansion-panels作为列表项。(如果我错了,请纠正我)
我的HTML代码如下
<mat-nav-list>
<mat-list-item>
<mat-expansion-panel>
<mat-expansion-panel-header>
<mat-panel-title>
Personal data
</mat-panel-title>
<mat-panel-description>
Type your name and age
</mat-panel-description>
</mat-expansion-panel-header>
<mat-form-field>
<input matInput placeholder="First name">
</mat-form-field>
<mat-form-field>
<input matInput placeholder="Age">
</mat-form-field>
</mat-expansion-panel>
</mat-list-item>
<mat-list-item>
<mat-expansion-panel (opened)="panelOpenState = true"
(closed)="panelOpenState = false">
<mat-expansion-panel-header>
<mat-panel-title>
Self aware panel
</mat-panel-title>
<mat-panel-description>
Currently I am {{panelOpenState ? 'open' : 'closed'}}
</mat-panel-description>
</mat-expansion-panel-header>
<p>I'm visible because I am open</p>
</mat-expansion-panel>
</mat-list-item>
</mat-nav-list>
如果有人能为我提供解决这个问题的方法,我将感激不尽。
您可以迭代使用mat-list-item而不是使用mat-list-item,并且可以同样添加扩展面板
<div *ngFor="let hero of herolist">
<mat-expansion-panel>
// here you can do whateever you want
</mat-expansion-panel>
</div>
如果你想用sidenav实现它,你可以拥有它
<ng-container>
<mat-side-nav>
</mat-side-nav>
</ng-container>
