This is useful I find to get all the top-level keys available in the current context: <ol> {% for key, value in _context %} <li>{{ key }}</li> {% endfor %} </ol> Thanks to https://www.drupal.org/node/1906780

Have you tried attr? {{ form_start(form, {‘attr’: {‘id’: ‘form_person_edit’}}) }}

Just change default delimiters for vue. Here’s how: Vue.js 1.0 Define delimiters globally (docs). Vue.config.delimiters = [‘${‘, ‘}’] Vue.js 2.0 Define delimiters for component (docs). new Vue({ delimiters: [‘${‘, ‘}’] }) Vue.js 3.0 Define delimiters for application (docs). Vue.createApp({ delimiters: [‘${‘, ‘}’] })

You are doing everything right, except passing your bundle path to asset() function. According to documentation – in your example this should look like below: {{ asset(‘bundles/webshome/css/main.css’) }} Tip: you also can call assets:install with –symlink key, so it will create symlinks in web folder. This is extremely useful when you often apply js or … Read more
A hyphen (or dash) at the end of a Twig block means to trim trailing whitespace, at the beginning, leading whitespace. Both means… both. See the Whitespace Control section of the docs; their example: {% set value=”no spaces” %} {#- No leading/trailing whitespace -#} {%- if true -%} {{- value -}} {%- endif -%} {# … Read more
