Angular Material Tooltips

Seeking help on showcasing an array of elements in a list format using mat-angular tooltip.

This code snippet belongs to app.component.html

<button mat-raised-button
      matTooltip={{items}}
      aria-label="Button that displays a tooltip when focused or hovered over">
      Action
</button>

The following code can be found in app.component.ts

items=['A','B,'C']

Currently, the array elements are displayed as comma-separated values. What I need is to display them in a list format with each element on a new line.

Appreciate any assistance, thank you!

Answer №1

To effectively showcase the array, consider displaying it in a new line each time. The documentation mentions that ::ng-deep is deprecated but still functional with the latest version.

Additionally, breaking lines after each word can be achieved by utilizing Array.prototype.join,

 items=['A','B','C'];
 newItems = this.items.join("\r\n");

Answer №2

One way to concatenate an array of strings in JavaScript is by using the join method of the Array. This method allows you to specify a delimiter that will separate each string in the final output:

<button mat-raised-button
        [matTooltip]="items.join()"
        aria-label="Button that displays a tooltip when focused or hovered over">
  Action
</button>

Answer №3

It's worth giving this task a shot for me app.component.html

<button mat-raised-button
   matTooltip={{items.toString()}}
   aria-label="Button that displays a tooltip when focused or hovered over">Action
</button>

app.component.ts

items=['A','B,'C']
