Hi.
Thank you Christoph for your reply.
I tried to use this solution and it works.
Only the selected items appear.
But if I want to modify this list, I have only these elements not all !
I hope that you have understand me.
Thank you a lot in avance.

Best regards.

Amine.

How do you do that, with <select multiple="true" > ?


In that case you can use struts tags like this:

<s:select
     multiple="true"
     name="allColors"
     list="selectedColors"
/>
