Ways to shift placeholder text slightly to the right within a select dropdown?

Struggling with this issue for hours, I can't seem to figure out how to:

  1. Adjust the position of the placeholder text (Search) by 10 pixels to the right in my select component
  2. Reduce the height of the field (maybe by 5px) without success.

Could someone please direct me in the right way? Thank you in advance! Here's the code I have:

LIVE DEMO

<mat-form-field [floatLabel]="'never'">
  <mat-label>Select</mat-label>
  <mat-select disableOptionCentering
    panelClass="my-mat-select-container">
    <mat-option *ngFor="let food of foods" [value]="food.value">
  {{food.viewValue}}
    </mat-option>
  </mat-select>
</mat-form-field>

Answer №1

If you want to achieve a custom styling with Angular Material, you'll need to overwrite some of the style classes.

I've made some modifications below, you can add the following CSS classes in your styles.scss file to see if it gives you the desired result.
Feel free to adjust the pixel values to fine-tune the labels.

// dropdown label 
.mat-form-field-label {
  padding-left: 10px;
}

// dropdown label 
.mat-form-field-flex {
  padding-top: 6px!important;
}

// dropdown label 
.mat-form-field-appearance-fill .mat-form-field-infix {
    padding-bottom: 6px!important;
}

// dropdown options style
.mat-select-panel .mat-optgroup-label, .mat-select-panel .mat-option {
    height: 38px!important;
}

// dropdown options style
.mat-select-panel .mat-option {
    padding-left: 25px !important;
}

// selected value text style
.mat-select-value-text {
   padding-left: 10px !important;
}

For better CSS handling without imports, make sure to provide explicit CSS directives. For example, for the code snippet below:

<custom-directive>
   <mat-label >Select</mat-label>
</custom-directive>

, you should write the CSS directive as follows:

custom-directive mat-label {
  // your CSS rules here
}

You can use the inspect element feature in Chrome to identify the correct CSS selectors, as shown in the example image below.

Answer №2

To adjust the position of the placeholder text, you can use padding as shown below

::ng-deep .mat-input-element label.mat-label {
  padding-left: 10px;
}

For controlling the height, you may try

::ng-deep .mat-input-container .mat-input-element .mat-input-flex {
  height: 50px;
}
