Hi Laxman,

You can try to use following forge component, it has the capability to enable/disable double click to show all records.

Hope it helps, Thanks

Hi Laxman,

You can customize the AutoComplete javascript (making a clone of the RichWidgets) or use a forge component.

This component is an improvement to the platform's AutoComplete and has the option to disable double click.

Hi Laxman,

You can also use the following javascript to disable double click of autocomplete input.

Just place following script in your Webscreen Javascript properties as shown in screenshot

document.addEventListener( 'dblclick', function(event) {  
    event.preventDefault();  
    event.stopPropagation(); 
  },  true 
);

Hope it works, Thanks :)
