Hi,

i want to develop a drop down chain box, which should be chained.
for example the first drop box will having a all country list and on selecting country "India" the next select box will list all state in india and on selecting state, the third select box should show city.

The list should come from mysql db.

Yes it can be coded for unlimited levels. You need to code in that manners.
