In this tutorial we will discuss Add Remove multiple textfield with jquery ,I think you’re looking for something like the below. The idea is to, on load, store a copy of the first row in a data attribute on the add link. Later, when you click the link, make a copy of that and add it to the container. Then just make the remove link drop the last row from the container when clicked.
Use j query Cdn file : https://code.jquery.com/
