[TYPO3] Menu with additional parameter and real_url compatible needed

[Pierre Rouwens]

Hi T3ers,

I need a jump menu select, real_url compatible. But in this case, i need 
the menu to go to the current page and i need to add only some parameters.
For example :
I'm on the page id=234 and the menu must be something like :
-----
<select name="cbSecteur" onchange="MM_jumpMenu('parent',this,0)">
<option value="index.php?id=234">All</option>
<option value="index.php?id=234&amp;sec=1&amp;no_cache=1">Sec 1 
only</option>
<option value="index.php?id=234&amp;sec=2&amp;no_cache=1">Sec2 only</option>
</select>
-----
Of course i need a way to make it real_url compatible :S:S I'm really lost.
And to complicate all of this, the "sec" is a field in pages i added via 
extension of the TCA. So i need it to loop about all value possible (1 
to 15) ...
I have searched a lot in the mailing list and googled it without any luck.
If you have any idea ???

TIA

Pierre
