Tips for disabling animation on mat-select dropdown input

I am looking to customize the appearance of a mat-select input. Currently, when clicking on the arrow to expand the list, there is an animation that displays the options. I want to eliminate this animation from the mat-select input and instead have it behave like a traditional native HTML select element with a simple pop-up effect for the options. Unfortunately, I cannot use the native HTML select in this case.

<mat-form-field>
  <mat-select>
    <mat-option>option1</mat-option>
    <mat-option>option2</mat-option>
    <mat-option>option3</mat-option>
  </mat-select>
</mat-form-field>

css angular angular-material

After much trial and error, I finally found the solution to my issue:

To remove animation from mat-select, you can use the following CSS code:

.mat-select-panel {
  &.ng-animating {
    visibility: hidden;
  }

Angular Material allows for the usage of native select element within mat-form-field. Although it wasn't suitable for my case, you can still give it a try with this code snippet:

<mat-form-field appearance="fill">
  <select matNativeControl>
    <option value="option1">option1</option>
    <option value="option2">option2</option>
    <option value="option3">option3</option>
  </select>
</mat-form-field>

To mimic the native dropdown animation, I ended up creating a custom directive. Here's the code snippet for that:

<mat-form-field
    appearance="outline"
    class="select-form"
    appDropDown
>
    <mat-label>Label</mat-label>
    <mat-select
        panelClass="select-panel"
        placeholder="placeholder"
    >
      <mat-option value="option1">option1</mat-option>
      <mat-option value="option2">option2</mat-option>
      <mat-option value="option3">option3</mat-option>
    </mat-select>
</mat-form-field>
