Tailwind CSS Form Theme

Warning: You are browsing the documentation for Symfony 7.0, which is no longer maintained.

Read the updated version of this page for Symfony 7.2 (the current stable version).

Symfony provides a minimal form theme for Tailwind CSS. Tailwind is a utility first CSS framework and provides unlimited ways to customize your forms. Tailwind has an official form plugin that provides a basic form reset that standardizes their look on all browsers. This form theme requires this plugin and adds a few basic tailwind classes so out of the box, your forms will look decent. Customization is almost always going to be required so this theme makes that easy.

To use, first be sure you have installed and integrated Tailwind CSS and the form plugin. Follow their respective documentation to install both packages.

If you prefer to use the Tailwind theme on a form by form basis, include the form_theme tag in the templates where those forms are used:

        1

        {# ... #}
{# this tag only applies to the forms defined in this template #}
{% form_theme form 'tailwind_2_layout.html.twig' %}

{% block body %}
    <h1>User Sign Up:</h1>
    {{ form(form) }}
{% endblock %}
    

Customization

Customizing CSS classes is especially important for this theme.

Twig Form Functions

You can customize classes of individual fields by setting some class options.

        {{ form_row(form.title, {
    row_class: 'my row classes',
    label_class: 'my label classes',
    error_item_class: 'my error item classes',
    widget_class: 'my widget classes',
    widget_disabled_class: 'my disabled widget classes',
    widget_errors_class: 'my widget with error classes',
}) }}
    

When customizing the classes this way the defaults provided by the theme are overridden opposed to merged as is the case with other themes. This enables you to take full control of the classes without worrying about undoing the generic defaults the theme provides.

Project Specific Form Layout

If you have a generic Tailwind style for all your forms, you can create a custom form theme using the Tailwind CSS theme as a base.
