Question

I'm using ionic 2. I need to remove the bottom white line from the input field. This is my addVehicle.html page,

<form [formGroup]="addCustomerForm" (ngSubmit)="onSubmit(addCustomerForm)">
<ion-item class="ion-card">
  <ion-input type="text" placeholder="Owner Name" class="ion_input" formControlName="vehicle_cust_name" name="vehicle_cust_name"></ion-input>
  <ion-icon name="person-add" class="ion_icon" item-left small></ion-icon>
</ion-item>
<ion-item class="ion-card">
  <ion-input type="text" class="ion_input" placeholder="Vehical No" formControlName="vehicle_no" name="vehicle_no"></ion-input>
  <ion-icon name="car" class="ion_icon" item-left small></ion-icon>
</ion-item>
<ion-item class="ion-card">

  <ion-icon name="call" class="ion_icon" item-left small></ion-icon>
</ion-item>
<ion-item class="ion-card">

    multiple="false">
    <ion-option *ngFor="let brandId of brandIds.brand" [value]="brandId.brand_id">{{brandId.brand_name}}</ion-option>
  </ion-select>
  <ion-icon name="code" class="ion_icon" item-left small></ion-icon>

  <ion-select class="ion_input" placeholder="Type" formControlName="vehicle_vehicle_models_id" [(ngModel)]="vehicle_vehicle_models_id"
    multiple="false" (ionChange)="modelChanged(vehicle_vehicle_models_id)">
    <ion-option *ngFor="let loadModel of loadModels.types" [value]="loadModel.models_id">{{loadModel.models_name}}</ion-option>
  </ion-select>
  <ion-icon name="code-working" class="ion_icon" item-left small></ion-icon>
</ion-item>
<button ion-button color="primary_btn" type="submit" [disabled]="!addCustomerForm.valid" block>
    Add Vehicle
    </button>
<button ion-button color="secondary_btn" type="button" (click)="cancleClick()" block>
    Cancel
    </button>

I used

$text-input-md-highlight-color:false;

And this is my .css

.ion-card{
background-color: #101218;
border: 1px solid #4A4A4A;
margin:20px auto;
border-radius: 10px !important;
}
.ion_input{
color:#f4f4f4;
opacity: 0.6;
}
.ion_icon{
color:#f4f4f4;
opacity: 0.6;
font-size: 5px;
}
.home_back{
 background-color: #15161D;
}
.item-inner, ion-item {
 border-bottom-color: transparent !important;
 box-shadow: none !important;
 }

for remove that white line which the image shows you.But I can't remove it.Is there a suggestion to overcome this issue guys

Answer 1

You can now just add lines="none".

Example:

<ion-item class="ion-card" lines="none">

From: https://ionicframework.com/docs/api/item

Answer 2

Just include no-lines in ion-item. Just like below

<ion-item no-lines></ion-item>
