Regarding Contact Form 7

Hello everyone,

I am using this “Contact Form 7” plugin from long time. I want to know that, if I want to display dynamic content in checkbox value, e.g. Query string value in checkbox value, then How can I do that?

for normal php, this can be done like
<input name="checkbox1[]" value="<?=$_GET['my_value']; ?>" type="checkbox">

Thanks in Advance
