Can you elaborate more?

invoice report form view gives the following code:

<?xml version="1.0"?> <form string="Report"> <field name="ir_values_id" invisible="1"/> <sheet> <div class="oe_button_box" name="button_box"> <button name="create_action" string="Add in the 'Print' menu" type="object" attrs="{'invisible':[('ir_values_id','!=',False)]}" icon="fa-plus-square" help="Display an option on related documents to print this report" class="oe_stat_button"/> <button name="unlink_action" string="Remove from the 'Print' menu" type="object" attrs="{'invisible':[('ir_values_id','=',False)]}" icon="fa-minus-square" help="Remove the contextual action related this report" class="oe_stat_button"/> </div> <group> <group> <field name="name"/> <field name="report_type"/> </group> <group> <field name="model"/> <field name="report_name" attrs="{'invisible':[('report_type','=', 'controller')]}"/> <field name="report_rml" attrs="{'invisible':[('report_type','!=', 'controller')]}"/> </group> </group> <notebook> <page name="security" string="Security"> <field name="groups_id"/> </page> <page name="rml" string="RML Configuration" attrs="{'invisible':[('report_type','not in',['pdf','sxw'])]}"> <group> <group string="RML Report"> <field name="header"/> <field name="report_file"/> <field name="auto"/> <field name="parser"/> <field name="usage"/> </group> <group string="XML Report"> <field name="report_xsl"/> <field name="report_xml"/> </group> </group> </page> <page name="advanced" string="Advanced Properties"> <group> <field name="multi"/> <field name="attachment_use" attrs="{'invisible':[('report_type','=', 'controller')]}"/> <field name="attachment" attrs="{'invisible':[('report_type','=', 'controller')]}"/> </group> </page> </notebook> </sheet> </form>

What exactly do I need to change? can you give an example?

thanks in advance.
