I would like to populate subsequent <select> tags based on user selections
<td>
<select id="cat" name="cat">
 <option value=""></option>
 <% for (int i=0;i<allcat.size();i++)
    {
      ecodes p = (ecode)allcat.get{i); %>
     <option value="<%=p.getcat()%><%=p.getcat()%></option>
    }
%>
</td>

<td>
<select id="area" name="area">
 <option value=""></option>
 <% for (int i=0;i<allcat.size();i++)
    { ArrayList allarea = cs.selectArea(SELECTED value from "cat");
    ...

?? I would like to pass the selected value from "cat". Can I do this? ??
     
    }
%>
</td>
Thanks,

No you cannot. This part of your code

 <% for (int i=0;i<allcat.size();i++)
    { ArrayList allarea = cs.selectArea(SELECTED value from "cat");

is JSP code on the server-side. And selection from the first select will happen on the client-side when the user selects it. This will be available to the server only when the user submits the form.
