如何在 Odoo14 中扩展 qweb 模板？

Question

I'm trying to add custom menu item in filter's dropdown list

in Odoo14 and owl framework some menu items exists in the base module inside the following snippet

<t t-name="web.CustomFilterItem" owl="1">
    <div class="o_generator_menu">
        <button type="button"
            class="o_add_custom_filter dropdown-item"
            aria-expanded="false"
            t-ref="fallback-focus"
            t-on-click="state.open = !state.open"
            t-on-keydown="_onKeydown"
            >
            <t>Add Custom Filter</t>
        </button>
    </div>
</t>

So in my custom module am doing the following to add custom item

<?xml version="1.0" encoding="UTF-8" ?>
<templates>
    <t t-extend="web.CustomFilterItem">
        <t t-jquery=".o_add_custom_filter" t-operation="after">
            <div
                role="separator"
                class="dropdown-divider o_generator_menu"
            />
            <button
                type="button"
                class="dropdown-item o_generator_menu o_add_advanced_search"
                aria-expanded="false"
            >Custom Item</button>
        </t>
    </t>
</templates>

But it doesn't appear. Any suggestions?

Odoo14 owl framework you can extend template using xpath.

you can use like this.

<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
<t t-name="CustomFilterItem" t-inherit="web.CustomFilterItem" t-inherit-mode="extension" owl="1">
<xpath expr="//button[hasclass('o_add_custom_filter dropdown-item')]" position="before">
//your code
</xpath>
</templates>
