Urgent !!! How to display empty multiselect rows dynamically in vf page

Hi All,

i am facing one issue where i need to add empty rows dynamically in vf page on button click. But it is not happening. Currently when i am clicking addrow button it is copying values from previous rows and displaying. And if i add some new values in 2nd row and then click addrow, all the rows are getting filled with all the values selected.

Below are the screenshot for clarification -

1. Filled up the first filled from multiselect and clicked addrow button -

This is likely happening because you are using the same variable when generating your individual line.  If you could please include the Visualforce page, that would help.
