Odoo 14: Add A Section Functionality In Tree View

I need add a section functionality like sales > quotation view has, in one of my tree views. . Code of my view is something like this:

<fieldname="qualification_lines"widget="section_and_note_one2many"><treeeditable="bottom"><control><createname="add_line_control"string="Add a line"/><createname="add_section_control"string="Add a section"context="{'default_display_type': 'line_section'}"/></control><fieldname="name"widget="section_and_note_text"optional="show"/><fieldname="display_type"invisible="1"/><fieldname="score"/></tree></field>

Model definition:

classQualification(models.Model):
    _name = 'hr.applicant.qualification'
    _description = 'Applicant Qualification'

    name = fields.Char(required=True)
    display_type = fields.Selection([
        ('line_section', "Section"),
        ('line_note', "Note")], default=False, help="Technical field for UX purpose.")

    qualification_data = fields.Many2one('hr.applicant', string='Qualification')
