我需要隐藏一个“分隔符”及其所有子项(树、字段、按钮等),我被卡住了,不知道如何实现这一点
<separator string="Quotations" />
<field name="purchase_ids" readonly="1">
<tree string="Purchase Order">
<field name="name" string="Reference"/>
<field name="date_order" string="Order Date"/>
<field name="partner_id"/>
<field name="company_id" groups="base.group_multi_company" widget="selection"/>
<field name="location_id" groups="stock.group_locations"/>
<field name="minimum_planned_date"/>
<field name="origin"/>
<field name="state"/>
<button name="purchase_cancel" states="draft,confirmed,wait_auth" string="Cancel Purchase Order" icon="gtk-cancel"/>
<button name="purchase_confirm" states="draft" string="Confirm Purchase Order" icon="gtk-apply"/>
<button name="purchase_approve" states="confirmed" string="Approved by Supplier" icon="gtk-ok"/>
</tree>
</field>
如果有人可以提供帮助,将不胜感激,非常感谢您!
