+This module allows to add an option `size` to Char fields in web client:
+
+.. code-block:: XML
+
+    <field name="sized_5_field" options="{'size': 5}"/>
+
+that allows to enter only the specified number of characters in the field.
+
+Note that adding the `size=` attribute in Char field definition raises the following warning:
+
+ unknown parameter 'size', if this is an actual parameter you may want to override the method _valid_field_parameter on the relevant model in order to allow it
