Hii,

Inherit the sale.order model and add a computed One2many field:

from odoo import models, fields, api

class SaleOrder(models.Model):

    _inherit = 'sale.order'

    filtered_order_line = fields.One2many(

        comodel_name='sale.order.line',

        compute='_compute_filtered_order_line',

        string='Filtered Order Lines',

        store=False,  # not stored, always computed

    )

    @api.depends('order_line.is_delivery')  

    def _compute_filtered_order_line(self):

        for order in self:

            order.filtered_order_line = order.order_line.filtered(lambda l: not l.is_delivery)

Inherit the original Sales Order form view (sale.view_order_form) and replace the existing order_line field with your new computed field filtered_order_line.

<record id="view_order_form_hide_delivery" model="ir.ui.view">

    <field name="name">sale.order.form.hide.delivery.lines</field>

    <field name="model">sale.order</field>

    <field name="inherit_id" ref="sale.view_order_form"/>

    <field name="arch" type="xml">

        <xpath expr="//page[@string='Order Lines']/field[@name='order_line']" position="replace">

            <field name="filtered_order_line" mode="tree,kanban" attrs="{'readonly': [('state', 'in', ('done','cancel'))]}">

                <tree editable="bottom" string="Sales Order Lines">

                    <field name="sequence" widget="handle"/>

                    <field name="product_id"/>

                    <field name="name"/>

                    <field name="product_uom_qty"/>

                    <field name="price_unit"/>

                    <field name="tax_id"/>

                    <field name="price_subtotal"/>

                    <!-- Optional: include is_delivery as invisible just for context -->

                    <field name="is_delivery" invisible="1"/>

                </tree>

            </field>

        </xpath>

    </field>

</record>

i hope it is usefull

Interesting question! I've tackled similar visibility issues. One approach is customizing the view definition using XPath expressions based on the 'is_delivery' boolean. Another simpler method might be leveraging computed fields & conditional formatting within Odoo's interface. If you're a fan of puzzles, this is like a code-based  

Hello,

Just as a suggestion: try to add a new field to sale.order.line which is 'active', the active field toggle the global visibility of the record as in the documentation , and you can do some changes that when the order line set to is_delivery toTrue then set the active to False

hope this could helps
