In many ways Odoo is easily configurable without even touching the code. Recently, a client asked if the drop down list can show All instead of the default 7 propositions.
A quick search and found this addon called web_m2x_options which adds new display control options to form fields.
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
