title: highlighting the text inside the textfield
body: <p>I want the text inside the textfield to be highlighted when I tap on it.</p>
  
  <p>I want the original text to be deleted the moment someone tap on the numberpad. I tried using clearButtonMode but then since my textfield size is very small the cross icon fully occupy the textfield.</p>
  
  <p>Any idea how to achieve this?</p>
