Disable scrolling bar in mat menu

Question

I am trying to make the scroll bar in a material menu disappear but I don't seem to be able to do it.

As it is right now:

As I want it to be:

I've tried the solutions proposed here and here, without success.

I know that the option I must set in the css is overflow: hidden; but this does not seem to do the trick when I put it in the component css.

I've tried setting that option to .mat-menu-panel, .mat-menu and even with a custom class, but it does not work.

My html looks like this:

<mat-table [dataSource]="dataSource">

      <ng-container matColumnDef="employee_name">
        <th mat-header-cell *matHeaderCellDef class="rest"> Nombre </th>
        <td mat-cell *matCellDef="let element"> {{element.employee_name}}</td>
      </ng-container>

      <ng-container matColumnDef="date">
        <th mat-header-cell *matHeaderCellDef class="rest"> Fecha </th>
        <td mat-cell *matCellDef="let element"> {{element.date | date:'yyyy-MM-dd'}}</td>
      </ng-container>

      <ng-container matColumnDef="duration">
        <th mat-header-cell *matHeaderCellDef class="rest"> Duración </th>
        <td mat-cell *matCellDef="let element"> {{element.duration}}</td>
      </ng-container>

      <ng-container matColumnDef="actions">
        <th mat-header-cell *matHeaderCellDef class="menu"></th>
        <td mat-cell *matCellDef="let element" (click)="$event.stopPropagation()">
          <button mat-icon-button [matMenuTriggerFor]="menu">
            <mat-icon>more_vert</mat-icon>
          </button>
          <mat-menu #menu="matMenu" class="menu-without-scroll">
            <button mat-menu-item (click)="editDuration(element)">
              <mat-icon>edit</mat-icon>
              <span>Editar</span>
            </button>
            <button mat-menu-item (click)="deleteDuration(element)">
              <mat-icon>delete</mat-icon>
              <span>Eliminar</span>
            </button>
          </mat-menu>
        </td>

      </ng-container>

      <tr mat-header-row *matHeaderRowDef="displayedComumns"></tr>
      <tr mat-row *matRowDef="let row; columns: displayedComumns;" (click)="onEdit(row)"></tr>
    </mat-table>

The menu is in one of the cells of the table.

From the developer tools in the browser if I change in .mat-menu-panel overflow: auto to overflow:hidden it renders correctly but if I change it in the .css it does not work.

The dependencies, in case it helps, are:

"dependencies": {
    "@angular/animations": "~7.0.0",
    "@angular/cdk": "^7.2.1",

Because , when you using angular one common attribute will be rendered in DOM like ng-content which will over write your class properties written in css , so try this code this will eliminate native angular styles to use in application .

Go to the Component,

import {ViewEncapsulation} from '@angular/core';

then

@Component({
.....
.....
encapsulation: ViewEncapsulation.None
})

then your styles will taken by browser .
