Adjust the appearance of matSelect when the selection menu is activated

What is the best way to adjust mat-select properties when its options are open?

<mat-select class="selector">
     <mat-option><mat-option>
</mat-select>

.selector:focus {
   color: green;
}

I attempted using focus, but it didn't work as expected since it could still be clicked without opening the options.

Solution: Resolved the issue by implementing

.mat-select[aria-expanded="true"] { 
    color: green 
}

Answer №1

By applying the CSS rule .mat-select[aria-expanded="true"] { color: green }, I was able to resolve the problem.
