I to All,
I am newbie in Dojo world...( In the past I have used Prototype + ScriptAcoulus..etc..)
And I have some problem for starting with this framework because the documentation (I have read in totally the dojobook) is poor...

I Would realize for my webpage a search module based on 3 ...

1) The first Select is a simple list of element
(For example :

chiave 1
chiave 2
chiave 3
)

a) If I apply whe dojit combobox for render my select with a good GUI...When the dojo render the tag SELECT ..lose the value of (key1,key2,key3)..It's Normal?

b) After the user choose the first select ..I would to "show" the second SELECT...and the value of this
second select is conditional by first select...How I can realize this with dojo?

(For Example :
if the user choose in the first SELECT the "key1" then Dojo must show the second SELECT with some value

word 1
word 2
word 3

if the user choose in the first SELECT the "key2" then Dojo must show the second SELECT with some value

pippo
pluto
silvestro

anb so...
)

2) When the User choose a value from the Second Select ...Dojo show the 3° SELECT that call a page in AJAX
with a Parameter and this Page return a JSON ... So that the content of this 3° SELECT is a result of a particullary key of JSON...

Then...Someone can Help me to translate or understand in Dojo language a solution form my simple problem?
(In prototype+script acoulus I have realized this code...)

Tnx for All
