Struts more html:select

[Dora Di Donato]

Hy guys,
I have in the same jsp more <html:select

the first is :

<html:select property="periodo" styleId="periodoId">
<htmlptions collection="periodi" property="key" labelProperty="value"/>
</html:select>

when I select a particular period (i.e. three months) in the other <html:select :

<html:select property="causale" onchange="resetStato(this);" style="margin-right:0;">
<htmlptions collection="operazioni" property="operationGroupId" labelProperty="nome"/>
</html:select>


I have to show automatically like causale property= "Scommesse".

How can do this?

thanks
