How to have an Ionic >=2 scrollable ion-list under fixed search bar

Issue

I have an Ionic >=2 application where I would like to have 2 or 3 fixed rows at the top of the page, and then have the rest of the page as a scrollable list (and later I want it to be virtual, but just want to get the simple list working forst).

As a simplified example, I have the following plunk. The markup repeated here is..

    <ion-header>
          <ion-navbar>
            <ion-title>{{ appName }}</ion-title>
           </ion-navbar>
    </ion-header>

    <ion-content scroll=false>
       <ion-grid>
         <!-- Row 1 fixed at top -->
         <ion-row>
           <ion-col>
             <ion-searchbar></ion-searchbar>   
           </ion-col>
           <!-- Other cols -->
         </ion-row>

        <!-- Row 2 Scrollable list -->
        <ion-row>
          <ion-col>
            <ion-list>    
              <ion-item *ngFor="let item of data">      
                <div>{{item}}</div>
              </ion-item>          
            </ion-list >  
          </ion-col>
       </ion-row>

       </ion-grid>
    </ion-content>

The problem is the search bar also scrolls with the list, whereas I would like this to always remain visible at the top of the page.

Does anyone know why I have the search bar also scrolling when this is in a completely separate row to the ion-list? Should I be using an ion-grid in this way?

Thanks in advance for any help!

Solution

ion-content does not have scroll input property to disable it.
If you need to have searchbar always visible, I suggest you place it in a toolbar.

<ion-header>
      <ion-navbar>
        <ion-title>{{ appName }}</ion-title>
       </ion-navbar>
       <ion-toolbar>
           <ion-searchbar></ion-searchbar>
       </ion-toolbar>
</ion-header>

Or use ion-scroll with a fixed height.

<ion-grid>
    <!-- Row 2 Scrollable list -->
    <ion-row>
      <ion-col>
          <ion-searchbar></ion-searchbar>
      </ion-col>
    </ion-row>
    <ion-row>
      <ion-col>
        <ion-scroll style="width:100%;height:100vh" scrollY="true">
           <ion-list scroll="true">
          <ion-item *ngFor="let item of data">
            <div>{{item}}</div>
          </ion-item>
        </ion-list>
        </ion-scroll>

      </ion-col>
    </ion-row>

  </ion-grid>

Sample Plunkr

Update: To answer @JohnDoe's comment.. in order to get scroll list to take the height of rest of the screen use Viewport percentage height to set the height of ion-scroll.
