Hi,

Please Use widget="section_and_note_one2many" in your One2many field in XML,

To Get Section and Note in Your Custom Model

and after applying it you can add the control

<field name="your_one_2_many_field"

widget="section_and_note_one2many"

      <tree editable="bottom" string="Journal Items">

       <control>

           <create name="add_line_control" string="Add a line"/>

<create name="add_section_control" string="Add a section" context="{'default_display_type': 'line_section'}"/>

<create name="add_note_control" string="Add a note" context="{'default_display_type': 'line_note'}"/>

       </control>

      // Add you custom fields

</tree>

</field>

Hope it helps
