  1. I have a dropdown list on each cell of table row. Now what I need is dynamically add more dropdownlist on a particular cells with pressing the add button. Any code snippet to help on this? Thank you.
  2. We have snippet of codes as below and able to add the row accordingly. In column 2 we have another add combo button which we wish to add copy of the combo and also to be able to delete it with also a <p> to later show if there is any error message. We are not able to do it dynamically when press the Add Combo button which suppose to the addSubRow function. Another thing we have this loop below and is showing [0] as undefined and [1] as the button whereas button is the first element in the cell?
