How to add a combo box dynamically at run time in Java script?..

Answer / rubin thomas

u cant add a combo box dynamically u can add option
dynamically. Also if u want to show a combo box which is
hidden u can do that using showhide() function in js to show
or hide this element. but the box must be present in your code
.
