I am in odoo18 and currently on the Receipt page. At the bottom section of this page, there is a tab called Operations which contains the product lines. I want to make this entire section read-only except for the hamburger icon (the “lot” action button) that allows adding lots to the products.



In hamburger button:


First, I used this code to make the entire section read-only, but it also disabled the hamburger icon, so I could not add lots at all:

<xpath expr="//field[@name='move_ids_without_package']" position="attributes">
    <attribute name="readonly">
        state == 'done' or approval_editable_has_po != 'edit_approved'
    </attribute>
    <attribute name="force_save">1</attribute>
</xpath>

Then, I changed the code by setting each individual column to read-only, leaving only the hamburger icon editable:

<xpath expr="//field[@name='move_ids_without_package']/list/field[@name='product_id']" position="attributes">
    <attribute name="readonly">parent.state == 'done' or parent.approval_editable_has_po != 'edit_approved'</attribute>
    <attribute name="force_save">1</attribute>
</xpath>

(…and similar XPaths for other columns)

The result is: all columns are read-only, so users cannot add new products — which is correct — and the hamburger icon still works, which is also what I want.

However, I also want to hide the “Add a line” button.

I tried:


<xpath expr="//field[@name='move_ids_without_package']/list" position="attributes">
    <attribute name="create">0</attribute>
</xpath>

This hides Add a line, but it disappears permanently.


Then I tried adding conditions:

<xpath expr="//field[@name='move_ids_without_package']/list" position="attributes">
    <attribute name="create">
        parent.state != 'done' or parent.approval_editable_has_po == 'edit_approved'
    </attribute>
</xpath>


But this does not work — look like the create attribute seems to accept only True/False/1/0 and ignores domain-like expressions.

My question is:

Is it possible to hide the “Add a line” button conditionally (based on state and approval fields) while still keeping the hamburger icon editable?

Hello there,

Check this,

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record id="view_picking_form_inherit_restrict_new" model="ir.ui.view">
        <field name="name">stock.picking.restrict.new</field>
        <field name="model">stock.picking</field>
        <field name="inherit_id" ref="stock.view_picking_form"/>
        <field name="arch" type="xml">
            <xpath expr="//field[@name='move_ids_without_package']" position="attributes">
                <attribute name="options">{'create':[('state','not in',['done','cancel'])]}</attribute>
            </xpath>
        </field>
    </record>
</odoo>


Hope this helps you.

Hello PhongsakornChe
I hope you are doing well

Yes, but it requires JavaScript (Odoo 18)

XML alone cannot do this - create attribute only accepts True/False, not conditions.

Solution: JavaScript + XML
static/src/js/list_renderer.js
  /** @odoo-module **/
  import { patch } from "@web/core/utils/patch";
  import { ListRenderer } from "@web/views/list/list_renderer";

  patch(ListRenderer.prototype, {
      get canCreate() {
          const ctx = this.props.list.context;
          // Hide "Add a line" when state is done AND not edit_approved
          if (ctx.parent_state === 'done' && ctx.parent_approval !== 'edit_approved') {
              return false;
          }
          return super.canCreate;
      }
  });

views/stock_picking_view.xml (pass context)
  <xpath expr="//field[@name='move_line_ids']" position="attributes">
      <attribute name="context">{
          'parent_state': parent.state,
          'parent_approval': parent.approval_editable_has_po
      }</attribute>
  </xpath>

  'assets': {
      'web.assets_backend': [
          'your_module/static/src/js/list_renderer.js',
      ],
  },

I hope this information helps you

Thanks & Regards
