I have incorporated Angular Material into my Angular 2 project, and I am trying to insert a static image (HTML element) in the selected value of mat-select. Unfortunately, I have been unable to find a solution for this issue.
Is there anyone who can offer assistance?
in situations like this, my approach is as follows:
<mat-form-field>
<mat-select [(value)]="selectedLanguage">
<mat-select-trigger>
<span class="flag-icon flag-icon-{{ selectedLanguage | lowercase}}"> </span>
</mat-select-trigger>
<mat-option *ngFor="let lang of Languages" [value]="lang">
<span class="flag-icon flag-icon-{{ lang | lowercase}}"></span>
</mat-option>
</mat-select>
</mat-form-field>
certainly, within the <mat-select-trigger> tags, you can use any other tags like img, and they will still function correctly!!
To incorporate an image within a <mat-option> tag, you can simply nest an <img> tag inside it. Use the ngClass directive to set the image as a background for the selected option. Make sure to assign one class per option:
HTML
<mat-select [(value)]="selected" [ngClass]="selected">
<mat-option>None</mat-option>
<mat-option value="option1">Option 1
<img width="10" height="10" src="https://upload.wikimedia.org/wikipedia/commons/f/f9/Phoenicopterus_ruber_in_S%C3%A3o_Paulo_Zoo.jpg">
</mat-option>
<mat-option value="option2">Option 2
<img width="10" height="10" src="https://raw.githubusercontent.com/mdn/learning-area/master/html/multimedia-and-embedding/images-in-html/dinosaur_small.jpg">
</mat-option>
<mat-option value="option3">Option 3</mat-option>
</mat-select>
CSS:
.option1{
background: url("https://upload.wikimedia.org/wikipedia/commons/f/f9/Phoenicopterus_ruber_in_S%C3%A3o_Paulo_Zoo.jpg") center / contain no-repeat;
white-space: nowrap
}
.option2{
background: url("https://raw.githubusercontent.com/mdn/learning-area/master/html/multimedia-and-embedding/images-in-html/dinosaur_small.jpg") center / contain no-repeat;
white-space: nowrap;
display:inline
}

Check out the Mat Select Trigger documentation here: https://material.angular.io/components/select/api#MatSelectTrigger
<mat-form-field>
<mat-label>....</mat-label>
<mat-select [formControl]="fromControl">
<mat-select-trigger>
<img src="assets/images/currencies/{{fromControl.value}}.svg">
<span>{{fromControl.value}}</span>
</mat-select-trigger>
<mat-option>
<img src="imageSrc">
<span>...</span>
</mat-option>
</mat-select>
</mat-form-field>
To enhance the functionality, it is suggested to enclose a <span> tag within both the <mat-select-trigger> and <mat-option> elements. Subsequently, you can bind HTML content to it using the method recommended in this solution.
<mat-select>
<mat-select-trigger>
<span [innerHTML]="myHtmlWithImageTag"></span>
</mat-select-trigger>
<mat-option *ngFor="let item of items" [value]="item">
<span [innerHTML]="myHtmlWithImageTag"></span>
</mat-option>
</mat-select>
