Dear Bullant,
Here is my link
http://183.78.169.54/v3/addRoute.php. First you can try to press the add button you will notice a new row of select box comes out. Now when you press submit is where I want to validate each row the select box should be selected. I have tried like this <select class='required' id='locationFrom[]' name='locationFrom[]' > but is not working. Any idea? So jquery will require more lines is it ?
