Restrict the number of choices in a drop-down menu using Angular

Is it possible to limit the number of results displayed in a dropdown select tag and add a scrollbar if there are more options?

Check out my code below:

   <select class="form-control" name="selectedOption" [(ngModel)]='selectedOption'>
        <option value="" [disabled]="true">Disabled</option>
        <option value="">All Options</option>
        <option *ngFor="let name of options" [ngValue]="name">{{name}}</option>
      </select>

I'm looking to initially display 8 results with a scrollbar for any additional options. If this isn't achievable with the select tag, what would be the best alternative method? Perhaps using a dropdown with links within a div and applying overflow on the div? What suggestions do you have for solving these challenges effectively?

Thank you.

To manage the limit of options, utilize both onmousedown and onblur events

<select onmousedown="if(this.options.length>8){this.size=8;}" onchange="this.blur()"  onblur="this.size=0;" class="form-control" name="selectedOption" [(ngModel)]='selectedOption'>
        <option value="" [disabled]="true">Disabled</option>
        <option value="">All Options</option>
        <option *ngFor="let name of options" [ngValue]="name">{{name}}</option>
</select>
