How to hide/delete underline input Angular Material?

Question

I have input element in Angular Material:

Answer 1

you can set your appearance to none in mat-form-field tag like this :

<mat-form-field class="header-search-form-field" appearance="none">
    <mat-label>search</mat-label>
    <input matInput placeholder="add product/>
</mat-form-field>

Answer 2

The other answers didn't work for me, but this did:

md-input-container input {
        border: none;
}

Answer 3

This worked for me:

::ng-deep .mat-form-field-underline {
    display: none;
}

Add it to the component's scss or css

Answer 4

This worked for me

.mat-form-field-appearance-legacy .mat-form-field-underline {
    height: 0 !important;
}

Answer 5

I was playing a bit with the appearance property of mat-form-field and found that if you put a "none" value (or any other unsupported value), you will get clear input.

The code:

  <mat-form-field appearance="none">
    <mat-label>"None" form field</mat-label>
    <input matInput placeholder="Placeholder">
  </mat-form-field>

StackBlitz demo (edited from the official angular demo).

The original example can be found here: Form field appearance variants.

I admit, this is a little bit of a hack.

Answer 6

::ng-deep .mat-form-field-underline {
  display: none;
}

the above code will remove the default black underline

::ng-deep .mat-form-field-ripple {
  display: none;
}

this will remove the on focus ripple effect
