problem with mdb-error overlaping field in horizontal form

Dear @Statie George

You can try to assign bootstrap margin-bottom to each form-row, like in my example below:

HTML:

<form [formGroup]="form" autocomplete="off">
      <div class="form-row mb-2">
        <div class="col">
          <label for="customerName" class="col-form-label-sm m-0" translate>CustomerName</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input
              mdbInput
              mdbValidate
              type="text"
              formControlName="name"
              class="form-control-sm"
              id="customerName"
            />
          </div>
        </div>
      </div>
      <div class="form-row mb-2 ">
        <div class="col">
          <label for="street" class="col-form-label-sm m-0" translate>Street</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input
              mdbInput
              mdbValidate
              type="text"
              formControlName="street"
              class="form-control-sm"
              id="street"
            />
            <mdb-error *ngIf="input.invalid && (input.dirty || input.touched)"
              >Input invalid</mdb-error
            >
          </div>
        </div>
      </div>
      <div class="form-row mb-2">
        <div class="col">
          <label for="houseNumber" class="col-form-label-sm" translate>HouseNumber</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input mdbInput mdbValidate type="text" class="form-control-sm" id="houseNumber" />
          </div>
        </div>
      </div>
      <div class="form-row mb-2">
        <div class="col">
          <label for="city" class="col-form-label-sm" translate>City</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input mdbInput mdbValidate type="text" class="form-control-sm" id="city" />
          </div>

        </div>
        <div class="col">
          <div class="md-form m-0">
            <input mdbInput mdbValidate type="text" class="form-control-sm" id="postalCode" />
          </div>
        </div>
      </div>
      <div class="form-row mb-2">
        <div class="col">
          <label for="postalCode" class="col-form-label-sm" translate>Email</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input mdbInput mdbValidate type="text" class="form-control-sm" id="email" />
          </div>
        </div>
      </div>
      <div class="form-row mb-2">
        <div class="col">
          <label for="phone" class="col-form-label-sm" translate>Phone</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input mdbInput mdbValidate type="text" class="form-control-sm" id="phone" />
          </div>
        </div>
      </div>
      <div class="form-row mb-2">
        <div class="col">
          <label for="ssn" class="col-form-label-sm" translate>SSN</label>
        </div>
        <div class="col">
          <div class="md-form m-0">
            <input mdbInput mdbValidate type="text" class="form-control-sm" id="ssn" />
          </div>
        </div>
      </div>
    </form>

TS:

 form: FormGroup;

  shouldShowValidationErrors(control: AbstractControl) {
    return control.invalid && (control.dirty || control.touched);
  }
  ngOnInit() {
    this.form = new FormGroup({
      street: new FormControl(null, [Validators.required]),
      name: new FormControl(null, [Validators.required]),
    });
  }

  get input() {
    return this.form.get('street');
  }
