hello there,
 

I would want to change the limit of 80 in the fields list here.

thanks to help

EDIT #1

The list of fields is defined in the view base.view_model_form. In the XML, we have this code. Can we define a limit in a XML file?

                        <page string="Fields">
                            <field name="field_id">
                                <tree string="Fields Description">
                                    <field name="name"/>
                                    <field name="field_description"/>
