+
+Example:
+
+.. code-block:: xml
+
+ <?xml version="1.0" encoding="UTF-8" ?>
+ <odoo>
+ <record id="view_users_tree" model="ir.ui.view">
+ <field name="model">res.users</field>
+ <field name="inherit_id" ref="base.view_users_tree"/>
+ <field name="arch" type="xml">
+ <xpath expr="//tree" position="attributes">
+ <attribute name="duplicate">true</attribute>
+ </xpath>
+ </field>
+ </record>
+ </odoo>
+
+Usage
+=====
+
+To use this module, you need to:
+
+#. Go to any tree view;
