add a start option for dynamic drop down list

hanyelbana

Hi,

I need to add a start option with null value to generated dropdown list like ( Please select country from the list ...)

editor.field('country_id').update( json.countries );

That will be good for validation and sometimes I need to let user to select null.

How can I add this option from the client code not from the database.

Thanks

You can't really add a `null` option, but you can add an empty string which might be okay for you? You can't add `null` specifically since HTML / HTTP don't understand Javascript null.

[code]
json.countries.unshift( {
label: 'Please select country from the list...',
value: ''
} );
[/code]

Just before you call the update function.
