how to disable "create and Edit from..." from a menu

Ex. when create timesheet under summery tab and when i add line i find the projects already created and at the end "Create and Edit...". i dt want this option available there.

i find an answer:

There is a module for openerp 6.1 to remove the create and edit option(in the openerp apps site search for web remove) from the default selection of many2one field. You can use this as an example and create you own module. or you can modify the base codes goto your server, then navigate to openerp/addons/web/static/src/js/view_form.js and remove the quick create functionality defined from the line number 2860.

but it remove create and edit from all menus over system i want to do that on just one menu like account when i add line in timesheet

thanks. :)
