positioning layers

[txingu186]

Hi,
I know that there are a lot of threads like this but I can´t resolve my problem.

Suppose that i have this html form:

...
<td>
        <fieldset>
            <legend>Other Info </legend>
            <table><tr><td><label for="links">Links:</label></td>
            <td id="links">
                <div name = "main" style="position:relative;">
                <div name ="en" style="position:absolute;">
                    <input type="text" name="links" id="links" size="25" tabindex="19" />
                    <input type="text" name="linkRef" id="linkRef" size="25" tabindex="20" value="http://"/>
                    <input type="button" value="+" onclick="crearAn('links',0)" /><br/>
                </div>
                <div name ="es" style="position:relative;">
                    <input type="text" name="links" id="links" size="25" tabindex="19" />
                    <input type="text" name="linkRef" id="linkRef" size="25" tabindex="20" value="http://"/>
                    <input type="button" value="+" onclick="crearAn('links',1)" /><br/>
                </div>
                </div>
            </td></tr></table>
        </fieldset>
        </td>
...
 

I used radio bottons to select <div en> or <div es> and the javascript is that:

function crearAn(obj,child) {
          num++;
          fi = document.getElementById(obj);
          //fi.appendChild(document.createElement('br'));
          ele = document.createElement('input');
          ele.type = 'text'; 
          ele.name = obj;
          ele.id = obj+num;
          ele.size = '25';
          fi.childNodes[0].childNodes[child].appendChild(ele);
          if (obj =="links"){
            ele = document.createElement('input');
            ele.type = 'text'; 
            ele.name = "linkRef";
            ele.id = "linkRef"+num;
            ele.size = '25';
            ele.value = 'http://';
            fi.childNodes[0].childNodes[child].appendChild(ele);
            fi.childNodes[0].childNodes[child].appendChild(document.createElement('br'));
          }
          else fi.childNodes[0].childNodes[child].appendChild(document.createElement('br'));
        }
 

I want to see only one div at time. so, only <div en> or <div es>. Well I have achieved it with the style of the div tags, but... if i add more than one input text element in <div en>, the fieldset doesn't make bigger.

"Lo siento mi inglés, me gustaría dobreexponer un div encima del otro. De la forma en que lo he escrito lo sobreexpone bien, pero el fieldset no sé agranda en el caso del <div en> ya que su position es absolute, si fuera relative estaría bien pero en ese caso no se sobreexpondrían. No sé si me he explicado bien"

Thanks
