+==================================
+Add new options for many2one field
+==================================
+
+
+Description
+-----------
+
+This modules modifies "many2one" form fields so as to add some new display
+control options.
+
+**New: support many2manytags widget ! **
+
+Options provided includes possibility to remove "Create..." and/or "Create and
+Edit..." entries from many2one drop down. You can also change default number of
+proposition appearing in the drop-down. Or prevent the dialog box poping in
+case of validation error.
+
+If not specified, the module will avoid proposing any of the create options
+if the current user have no permission rights to create the related object.
+
+
+Requirements
+------------
+
+Was tested on openerp v7.0
+
+
+New option
+----------
+
+``create`` *boolean* (Default: depends if user have create rights)
+
+  Whether to display the "Create..." entry in dropdown panel.
+
+``create_edit`` *boolean* (Default: depends if user have create rights)
+
+  Whether to display "Create and Edit..." entry in dropdown panel
+
+``m2o_dialog`` *boolean* (Default: depends if user have create rights)
+
+  Whether to display the many2one dialog in case of validation error.
+
+``limit`` *int* (Default: openerp default value is ``7``)
+
+  Number of displayed record in drop-down panel
+
+
+Example
+-------
+
+Your XML form view definition could contain::
+
+    ...
+    <field name="partner_id" options="{'limit': 10, 'create': false, 'create_edit': false}"/>
+    ...
+
+Note
+----
+
+Double check that you have no inherited view that remote ``options`` you set on a field ! 
+If nothing work, add a debugger in the first ligne of ``get_search_result method`` and enable debug mode in OpenERP. When you write something in a many2one field, javascript debugger should pause. If not verify your installation.
