What is the best way to insert an image within a mat-select-trigger?

How can I dynamically insert two svg flag images into a mat-select-trigger based on the user's language selection? Here is my code for reference:

HTML

<div class="select-container">
        <mat-select class="select-language placeholder-light" [(value)]="selectedLanguage" #selLang (selectionChange)="setLang(selLang.value)" disableOptionCentering>
            <mat-option value="pt-br"&mt;
                <img class="img" [src]="'./assets/flagIcons/br_flag.svg'">
                {{ 'header.language.pt-br' | translate }}
            </mat-option>
            <mat-option value="en">
                <img class="img" [src]="'./assets/flagIcons/usa_flag.svg'">
                {{ 'header.language.en' | translate }}
            </mat-option>
        </mat-select>
    </div>

TS

constructor(private readonly translate: TranslateService) {}

     public setLang(lang: string) {
            this.translate.use(lang);
        }

Answer №1

To enhance the functionality, my suggestion is to enclose the mat-select within a mat-form-field element. For more details, visit: https://material.angular.io/components/form-field/overview

Specifically for your situation, you can utilize the matPrefix directive like this:

<mat-form-field>
  <mat-select>
    <mat-option value="value">
      <!-- Option text -->
    </mat-option>
  </mat-select>

  <span matPrefix>
    <!-- Insert your image here -->
  </span>
</mat-form-field>

Answer №2

Here is my solution to the problem.

<div class="select-container">
            <mat-select class="select-language placeholder-light" [(value)]="selectedLanguage" #selLang (selectionChange)="setLang(selLang.value)" disableOptionCentering>
                <mat-select-trigger>
                    <img [src]="selectedLanguage === 'en' ? './assets/flagIcons/usa_flag.svg' : './assets/flagIcons/br_flag.svg'">
                    {{ selectedLanguage === 'en' ? ('header.language.en' | translate) : ('header.language.pt-br' | translate) }}
                </mat-select-trigger>
                <mat-option value="pt-br">
                    <img class="img" [src]="'./assets/flagIcons/br_flag.svg'">
                    {{ 'header.language.pt-br' | translate }}
                </mat-option>
                <mat-option value="en">
                    <img class="img" [src]="'./assets/flagIcons/usa_flag.svg'">
                    {{ 'header.language.en' | translate }}
                </mat-option>
            </mat-select>
        </div>
