Here is a classic editable list in OpenERP v6.0 :
It’s a custom view I created this month at work for one of our customer to let him select a list of products, then batch-print their labels on stickers.
The view above is produced by the following XML :
If you start searching a product template with the first field, you’ll get a pop-up similar to this one:
As you can see, these kind of pop-up inherits the width of their parent field, which hide the end of all lines if they are too long. It becomes difficult to distinguish the items when all found objects have the same long prefix.
Now I want to get rid of this behavior and let the pop-up menu take all the necessary width it needs to fully display its content.
My instinct told me that this default style could easily be overridden with some static CSS directives. But digging deeper into OpenERP web client code , I realized that the width is dynamically set by the many2one widget itself.
The code responsible for this behavior is located in the addons/openerp/static/javascript/m2o.js file, in the ManyToOne.prototype.on_keydown method:
Python Static Method
My goal is now to alter this default behavior, without touching the code in m2o.js .
And thanks to Bryan Forbes’ article , I engineered a method to monkey patch the original ManyToOne.prototype.on_keydown Javascript method.
Here is the code I added in the XML view, just below the line_ids field:
The result of this is a nice looking pop-up which doesn’t break any vanilla Javascript of the OpenERP web client:

From this tutorial, you will get to learn about Python Static method. It is one of the essential concepts to use while you are learning OOPs programming with Python.
Note: The syntax used in the below section is for Python 3. You may change it to use with a different version of Python.

What is a static method in Python?
It is available as a built-in function in Python and allows you to turn a regular method into the static.
In other words, you can create a callable class using the static method and use it with some restrictions.
It helps developers write code in a safe architectural way to prevent conflicts in the code.

When you create a class, you usually define a few methods and properties. They may or may not have access to the class instance.
There three types of methods depending upon their access are Instance Method, Class Method, and Static Method. This tutorial will cover the application of Static Methods.
It is a method which does not have access to the class state. In other words, the method confines to itself and cannot change the properties of the class instance without any workaround.

You can make use of “staticmethod” in your programs with the following syntax:
Alternatively, you can follow the below syntax:
Program Examples
Function returning a value as static:
Here is a simple program to demonstrate static methods.
Save the above code as “staticmethod.py” and execute. The output will come as:
A method as static:
Check another program to use the built-in staticmethod() function.
Save the above code as “builtinstaticmethod.py” and execute. The output will come as:
