The Twital instruction for Twig use tag is t:use node.

This is a fature that allows a/the horizontal reuse of templates. To learn more about it, you can read the official documentation.

Let’s see how does it work:

<t:use from="bars.html"/>

<t:block name="sidebar">

You can create some aliases for block inside “used” template to avoid name conflicting:

<t:extends from="layout.html.twig">
    <t:use from="bars.html" aliases="sidebar as sidebar_original, footer as old_footer"/>

    <t:block name="sidebar">
        {{ block('sidebar_original') }}


For more information about the use tag, please refer to Twig official documentation.
