Perch form admin hide empty values

Hey,

I try make with JS form where you can add new input text but after submit form these inputs are not sending.

So, I just add these inputs into form and only hide them with css and after click on button "Add name" i fadeIn next input. I will have 20 inputs for start.

Now have problem in admin sometimes user need add only 3names (not all 20) but in admin is whole list. Is possible hide these empty rows and show only these which are filled?

Thanks
