Hola, os dejo el código que uso, a ver si veis algo que pueda solucionar el problema:
Código:
<table>
<tr>
<td>
<div>
<ul>
<li><a id="a1" href="#"><span id="ctl00_headerControl_lblHome">Home</span></a></li>
<li><a id="a2" href="#"><span id="ctl00_headerControl_lblProducts">Products</span></a>
<ul style="visibility: hidden;">
<li><a href=""><span id="ctl00_headerControl_P1">P1</span></a></li>
<li><a href=""><span id="ctl00_headerControl_P2">P2</span></a></li>
<li><a href=""><span id="ctl00_headerControl_P3">P3</span></a></li>
<li><a href=""><span id="ctl00_headerControl_P4">P4</span></a></li>
</ul>
</li>
<li><a id="a3" href="#"><span id="ctl00_headerControl_lblServices">Services</span></a>
<ul>
<li><a href="#"><span id="ctl00_headerControl_S1">S1</span></a></li>
<li><a href="#"><span id="ctl00_headerControl_S2">S2</span></a></li>
</ul>
</li>
</ul>
</div>
</td>
</tr>
<tr>
<td>
<span id="ctl00_cntMainContent_lblName" style="position:relative; margin-top:11px;">* Name</span>
<br />
<input type="text" maxlength="20" id="ctl00_cntMainContent_txtName" style="width:175px;position:relative;margin-top:0px;" />
<select id="ctl00_cntMainContent_ddlSector" style="width:175px;position:relative; margin-top:0px; margin-left:20px">
<option value="1">Sector1</option>
<option value="2">Sector2</option>
<option value="3">Sector3</option>
<option value="4">Sector4</option>
</select>
<br />
<span id="ctl00_cntMainContent_lblSurname" style="position:relative; margin-top:11px;">Surname</span>
<br />
<input type="text" maxlength="50" id="ctl00_cntMainContent_txtSurname" style="width:175px;position:relative; margin-top:0px;" />
<select id="ctl00_cntMainContent_ddlEmployees" style="width:175px;position:relative; margin-top:0px; margin-left:20px">
<option value="0">Employees</option>
<option value="1">1 to 10</option>
<option value="2">10 to 100</option>
<option value="3">100 to 500</option>
<option value="4">500 to 1000</option>
</select>
</td>
</tr>
</table>
Cómo os he dicho, los submenús se me muestran por debajo de los selects de la segunda fila.
Alguna idea?
Muchas gracias
