i have a scenario in JSP where i have to make a combo with a list containing 10 items say 1,2,3.... 10. now i select a combo. I also need to provide an add button that will add another combo with same elements except the one being selected in previous combo.

eg- if 1st combo selected value is 1 then in the next combo i'll have the list as 2,3,4.....10 i.e, having 9 elements and so on. the user can add 10 combos like this, each combo having the items that haven't been previously selected.

can anyone help me with this???
thanks in advance !!!

you can use a simple javascript code on any event you like to have(e.g click focus or blur etc) , the logic may vary as per your need. i would not prefer to do it with a java code in jsp since on browser i need a dynamic response without playing with request and response.

for information regarding javascript refer javascript examples

Using jQuery you would do something like this:



However, you'll need to think about what happens when the user goes back to one of the earlier select boxes and changes the value.

It is sorta covered in the JavaRanch Style Guide.
