Limiting Advance Search drop down list, please help ..

Hello,

We’re using RefMan 12 (Bld 2401), and was wondering if there’s an option in the software to limit the advance search drop down list to only few options (Please see attached screenshot). 

If not and if we have to edit an XML/HMTL/CSS file, can you please provide instructions on how to do so.  We are running RefMan on an XP machine SP3, and it’s running as a Windows Service.

thanks in advance for all of your help.

thank you,

Mo
