Hi All,

I am new here but I need your help in acheiving a goal concerning my pet website.

I have a combo box with some items listed e.g.
-Item A
-Item B
-Item C
-Item D

When a user selects a particular item, I want another combo box to be populated with another sets of items relating to the item selected in the first combo box field. For example,

if Item A is selected, then the second combobox should have the following lists
--Item A1
--Item A2
--Item A3
--Item A4

if Item B is selected, then the second combobox should have the following lists
--Item B1
--Item B2
--Item B3

if Item C is selected, then the second combobox should have the following lists
--Item C1
--Item C2
--Item C3
--Item C4

I hope my explanation is clear.

Please somebody should help me out.

Regards,
nicechap.

What you ask for requires some degree of experience or a tool to achieve.
You can do it in two ways:
1. Using Javascript, with embeddd in the page JaVascript. Have a look at http://www.dbtechnosystems.com/Tips/...drop_downs.php
This is a three level dependent drop down based on a script found (if i recall well) on Dynamic Drive and modified from the original two level.
2. Using Ajax (which is Javascript plus a server side programming language like php or Perl). Have a look at this application i made for a client of mine: http://www.evansconstructionpages.com/

When you select a State, the counties dropdown is automatically populated, the same for categories and subcategories. This is the best solution if you have too many values (in this case, thousands).

Search the net, there are dropdown creation tools if you have only a few values and you can make it with simple Javascript
