Hi
I am making a custom form, where I want to have work history of a person in one line and at the end of line a button "add more".
It will look some thing like as below -
 
Company         Start-Date      End-Date       Add More ...
 
If user clicks on button "Add More ..." then it should add one more line and my form should look as below
 
Company         Start-Date      End-Date       Add More ...
Company         Start-Date      End-Date       Add More ...
 
So how many times user clicks "Add More ...", those many rows should be shown up.
 
How can I acheive it  in Drupal. As per documentation and google search AHAH is capable of doing it.
Please correct me if wrong.
 
My custom form code is as below. My questions are - 
 
1. How can I add 4 fields in one line. By default these are coming  below of earlier field.
2. How to make use of AHAH.
3. Also  one more challenge for me is how do act on "onClick" of  "Add More ..." button, by default it may call submit handler.
 
A step by step approach will help me, as first time I am looking at AHAH.
 
 Best Regards
Austin
