问题描述
我注意到,如果容器对于选项卡来说太小,则在显示箭头时,MatTabNavBar的行为与常规MatTabGroup有所不同.
I've noticed that the MatTabNavBar is behaving different from a regular MatTabGroup when it comes to showing the arrows if the container gets too small for the tabs.
我使用官方文档来构建MatTabNavBar和MatTabGroup,但是您可以在此处看到MatTabGroup显示箭头,而MatTabNavBar没有箭头.
I used the official documentation to build the MatTabNavBar and MatTabGroup, but you can see here that the MatTabGroup is showing arrows and the MatTabNavBar is not.

用于MatTabGroup的模板:
Template used for MatTabGroup:
<mat-tab-group>
<mat-tab
*ngFor="let tab of tabs"
[label]="tab.label"
>
{{ tab.label }}
</mat-tab>
</mat-tab-group>
用于MatTabNavBar的模板:
Template used for MatTabNavBar:
<nav mat-tab-nav-bar>
<a
mat-tab-link
*ngFor="let tab of tabs"
[active]="isActive(tab)"
(click)="setActive(tab)"
>
{{ tab.label }}
</a>
</nav>
...所以我有什么想念的吗?预期的结果是MatTabNavBar显示与MatTabGroup相同的箭头.
...so am I missing anything?! The expected result is the MatTabNavBar showing the same arrows as MatTabGroup.
