How to Scroll one text and other in static using qml repeater??

[Bharathi]

Using Number animation I can able to scroll the single text or one more text in repeater.But I want to show that a single text is on scrolling and other in static.Any suggestions.
Here is my code

Rectangle
{
    id:root
    x:0
    y:0
    width:1024
    height:786

Repeater{
    id:rootmodel
    model:2

Text{
    id:text
    x:parent.width/2-text.width/2-xval[index]
    y:parent.height/2-text.height/2-yval[index]
    anchors.centerIn: parent.Center
    text:source[index];
    font.pointSize:200

    NumberAnimation on x
    {
        id:animate
        running:false
        from: root.width
        to: -1*text.width
        loops: Animation.Infinite
        duration: 16000
    }
}
}
Timer{
    id:timer
    interval: 1000
    repeat: true
    running: true
    onTriggered:
    {
      if(rootmodel.count>1)
      {
          rootmodel.itemAt(0).running=true;

      }

    }
}

}

@Bharathi How about adding a condition in NumberAnimation itself? For eg.

running: index==1 ? true:false //animates Item at index 1
