Require Wordpress Plugin Form Maker Pro Customization

Avg Bid (USD)
Project Budget (USD)
$10 - $30

Project Description:
I have purchased a wordpress plugin: "Form Maker Pro".
Details and Demo can be seen at:

I want a customization as follows:
Add the feature in admin to include the lines as per what you see in attached file? Including the possibility for user who fills the form, to add more lines if required. It is simple text area but first box which says "Qty" is of smaller size in width and the Second Box which says "Item Description" is wider.

There must be the option to increase or decrease the width and also option to change the text of both boxes like "Qty" or "Quantity" or "anything else", whatever admin wants.

There must be the option for admin to "set number of rows visible by default".

If require any further details, pls write.

Ok I have now managed to add the lines in the form using "text input" option and inserting "phone" as field type. (you will understand if you have seen the admin demo)

Now I only need you to add the button which says: "Add more rows" similar to what you can see in the attached picture.

To see the live form which I have installed on my website, pls visit:
