the example given
<s:doubleselect label="doubleselect test1" name="menu" list="{'fruit','other'}" doubleName="dishes" doubleList="top == 'fruit' ? {'apple', 'orange'} : {'monkey', 'chicken'}" />

has only two values in the first list that is fruit and other what if i have 10 items in the first list how should i write the
doubleList="top == 'fruit' ? {'apple', 'orange'} : {'monkey', 'chicken'}" />
part for that example..

and if a value is selected from the second list another combo box or a text box should be displayed according to the value selected.

You need to construct your logic based on ternary operator. It will be more complicated when the first list size increase. Still I provide a solution for your problem.

but the other way to use the doubleselect (its called OGNL method)

But very simple way is

Create a optionMap as a LinkedHashMap (because it have sorted order) in your action and use it.

Hope its solve your problem. Let me know if you need any clarification.
I agree. Here's the link:
