Hi Sathya
Yes you should use one model for each of your dropdowns.
Lets say you are creating a site where you can search for books.
Then you might have a drop down for author and maybe category.
I guess(without knowing anything about searching and or books:)) that I would
create a class that holds the search criteria eg:
search.java
private author
private category
getter & setter methods goes here
so on my wicket page i'll have the following pseudo code:
private Search bookSearch=new Search;
Imodel author=new Propertymodel("bookSearch.author",search);
Imodel category=new Propertymodel("BookSearchcategory",search);
dropdown dropAuthor=new dropdown(id, author);
add(drop)
dropdown dropCat=new dropdown(id,category);
add(drop)
button search=new Button(id){onsubmit(
process(search))
}
add(search)
I hope my simple example contributes to something usefull:)
Regards Nino

Subject: Re: [Wicket-user] Dropdown choices in wicket
Thanq Nino,
well, iam using a model to store the data , actually i was going through the
example given in the http://ensode.net/wicket_first_look.html , where in the
author creates two models , the first model to store the normal form values
and the second model explicitly to store the dropdown selected values
, so here my doubt is if there are around 5 drop down choices in a page,
then should i create 5 models for each to store the selected values?
