How to add row accodingly?
Here is my link http://220.127.116.11/tm/layout.php. I have two button "Add Single" and "Add Double".What I want is that when I press the "Add Single" a new row add with the single drop down list and when I press "Add Double" I would like to have the row with two drop down list. How to achieve this ? In the begining must I hide both the rows is it? Now I have the relevant function ready for both buttons but I do not know how to add the rows accordingly. Finally I also want to make sure all the dropdown list values selected is different.
