Is there a way to get rid of the extra width?

Here is my current code:

html:

<mat-form-field>
    <mat-select disableOptionCentering placeholder="Choose an option">
      <mat-option [value]="option" *ngFor="let option of my_list">
          {{ option }}
      </mat-option>
    </mat-select>
</mat-form-field>


my_list:

export const my_list: string[] = [ "a", "b", "c", "d"];


style.css:

.mat-select-panel{
    margin-left: 15px;
    margin-top: 28px;
}

Hi RikG93, I don't think two posts are talking about the same thing. Here I want to reduce the width of the scrollable panel. The answer in the link provides a solution to load more when scrolling down in the scrollable panel. - Meng
Did you ever figure this out? I am trying to do the same. - cheesydoritosandkale

For anyone still trying to figure out without making the actual select smaller or wider.

The mat-select-panel uses 100% of the mat-select width plus 32px

min-width: calc(100% + 32px)

You can override this styling with ng-deep:

::ng-deep .mat-select-panel {
    min-width: 100% !important;
}

   <mat-select style="width:10px">

.mat-select-panel:not([class*=mat-elevation-z]){ min-width: calc(100% + 0px) !important; }
