iterating thru a collection

I need to iterate thru a collection and put it in an <html-el:select>
field.  How do I go about doing this....

My collection type looks like this....

ArrayList options
int selectedOption

The ArrayList of options is the following type:

String label
int id

Can anyone help me???

Thanks in advance...

Not to sure what is required here but for populating a select box options
with values and labels
I just create a java.util.List of beans.

e.g. Category bean

public class Category {
    protected int id;
    protected String name;
    // getters/setters
}

Now you just load the List (e.g. categoryList of type java.util.List) into
the <options></options> tag specifying the value and label that will be
pulled out of the beans in the List. (e.g. value=Category.id;
label=Category.name)

something like that...:)

Looks like you need a Map, not a List.
