Tips for adjusting the size of Angular Material elements

In the midst of my work on an Angular application, I have been utilizing angular material components. However, as I delved into styling the application, I encountered difficulties in styling the angular material component, particularly in enlarging a dropdown created using mat-select and mat-options.

I am familiar with the solution involving ::ng-deep, but I am unable to pinpoint a specific part of the component that would resize the entire component. I am also open to exploring alternative methods to ::ng-deep if anyone is aware of any.

<mat-form-field>
  <mat-select [(value)]="initialValue" [placeholder]="placeholder">
    <mat-option class="mat-option" *ngFor="let option of content"
      [value]="option">
        {{option}}
    </mat-option>
  </mat-select>
</mat-form-field>

Here is a basic implementation of the angular material dropdown: https://stackblitz.com/edit/angular-cuu4pk

My attempts to use ::ng-deep to adjust the size of the component have only resulted in resizing the targeted css class, not the entire component.

edit: Thank you for the responses thus far! While I can modify the width of the component with ::ng-deep, the overall sizing remains the same even when adjusting the height. I am seeking a solution akin to css's transform: scale(). The challenge with using transform scale() lies in the distortion of the component.

Answer №1

To customize the width of "mat-form-field", you have two options:

<mat-form-field style="width: 400px"> // <---- Add your custom style here
  <mat-select [(value)]="initialValue" [placeholder]="placeholder" >
    <mat-option class="mat-option" *ngFor="let option of content"
      [value]="option">
        {{option}}
    </mat-option>
  </mat-select>
</mat-form-field>

Alternatively, you can add this code to your CSS file:

mat-form-field{
  width: 400px;
}

Answer №3

To make the component full width, you need to include the following CSS:

.mat-form-field {
    width: 100%;
}

This is necessary because the .mat-form-field class by default has the property display:inline-block;. Adding width: 100%; overrides this setting and makes the component stretch to the full width.
