Download the PHP package northwestern-sysdev/northwestern-filament-theme without Composer

A branded Filament theme plugin for Northwestern University applications. Applies the official NU color palette, typography, and institutional styling from Department Templates 4.0 to any Filament panel, and adds the required university footer.

Installation

Quick Start

Register the plugin in your Filament panel provider:

Then publish the theme assets:

[!NOTE]

If your panel has a custom theme via ->viteTheme(), it will continue to work alongside this plugin. The Northwestern theme is an additive CSS layer registered separately through Filament's asset system. It does not replace your custom theme.

Configuration

The theme's branding content lives in config/northwestern-filament-theme.php: your unit's lockup, its contact details for the footer, the footer's Quick Links and its social accounts. Publish it to edit it:

Config describes your unit. Per-panel behavior stays on the plugin: turning the footer off, the environment indicator and the impersonation banner.

Resolution Order

Each value resolves in this order:

1. A value passed to ->footer() or to the footer component's props. These are deprecated; see Deprecated Footer Arguments.
2. config('northwestern-filament-theme.*').
3. The legacy config('northwestern-theme.*') key, from northwestern-sysdev/northwestern-laravel-ui if it is installed.
4. The built-in default: Information Technology's contact details, no fax, no Quick Links, Northwestern's social accounts and the dept 4.0 wordmark.

null means "not set" and moves on to the next step. An empty string hides the field, and for lockup it means the wordmark. So an app that still has config/northwestern-theme.php keeps working without changes, and anything you set in the new file wins over it.

Moving From northwestern-theme.php

Apps built on starter v2 have a config/northwestern-theme.php published by northwestern-laravel-ui. The theme still reads it, so moving is optional in 4.x. To move, publish the new file and copy each value across:

The legacy file's sentry-dsn, sentry-enable-apm-js, sentry-traces-sample-rate and globalAlerts keys belong to northwestern-laravel-ui, not to this theme, and have no equivalent here.

The legacy lockup default in northwestern-laravel-ui is the v8 wordmark URL. Once the legacy file is gone, an unset lockup gives the dept 4.0 wordmark instead.

Vite Theme Integration

You can also import the theme directly into your panel's Vite-compiled stylesheet instead of loading it as a separate <link> tag. This gives you a single compiled CSS bundle, access to Northwestern design tokens as Tailwind v4 utility classes (e.g., bg-nu-purple-100, text-nu-gold), and the ability to override specific theme styles in your own CSS.

Setup

Run the install command:

This will:

• Create a panel theme CSS file if one doesn't exist
• Inject the Northwestern theme @import after the Filament base import
• Optionally inject Tailwind v4 design tokens for color utilities

Then disable automatic asset registration in your panel provider to prevent the CSS from loading twice:

Finally, compile your assets:

Tailwind v4 Design Tokens

When you opt in to design tokens during northwestern-theme:install, the plugin provides Northwestern colors and fonts as Tailwind v4 utility classes:

Available token groups:

[!NOTE]

Design tokens require Tailwind CSS v4+ (they use the @theme syntax). The core theme CSS works with any Tailwind version.

The palette, fonts and radius come from @nu-appdev/northwestern-tokens, which this package bundles into dist/ at build time. You don't install the npm package yourself.

Tokens Without Filament

dist/tokens.css contains only the Northwestern @font-face rules and the --nu-* custom properties, with no Filament selectors. Use it on pages that render outside a panel, such as an error layout, together with the footer component. Inside a panel you don't need it: dist/theme.css already includes it.

Dark Mode

The theme adapts to Filament's dark mode setting automatically. No extra configuration needed.

Favicon & Brand Logo

The plugin automatically sets a Northwestern favicon and brand logo when the panel has not already configured them. If you call ->favicon() or ->brandLogo() on your panel, your values take precedence.

The brand logo is resolved in the following order:

1. Panel-level ->brandLogo() (if set, the plugin does not override it)
2. The configured lockup (see Configuration), passed through asset()
3. The Department Templates 4.0 "Northwestern" wordmark, as inline SVG. It is Northwestern Purple on light backgrounds and white in the topbar and in dark mode.

The default favicon is https://common.northwestern.edu/favicon.ico, the icon dept 4.0 pages use.

If your application uses northwestern-sysdev/northwestern-laravel-ui, its legacy northwestern-theme.lockup value still applies when the new lockup is unset. Its default is the v8 wordmark URL, so set the legacy lockup to null, or move to the new config, to get the dept 4.0 wordmark.

Environment Indicator

The theme includes a built-in environment indicator that displays a gold badge and a colored top border on non-production environments: in the topbar of full pages, and at the top of simple pages such as login. This is enabled by default.

The indicator automatically hides in production. The topbar badge also hides on small screens.

Disabling the Indicator

Custom Visibility

To control when the indicator appears (e.g., only for admins):

Custom Label

By default, the badge reads "Environment: Local" (or whatever APP_ENV is set to). To customize:

[!NOTE]

If you are using pxlrbt/filament-environment-indicator, you can remove that package. Remove EnvironmentIndicatorPlugin::make() from your panel provider and the theme handles the rest.

Impersonation Banner

The theme includes a built-in impersonation banner that renders a red bar above the topbar when a user is being impersonated. It is registered by default and shows automatically when lab404/laravel-impersonate is installed and an impersonation session is active. Without lab404, the banner will not appear unless you provide a custom visible closure.

Custom Visibility

If you are not using lab404/laravel-impersonate, or want to override the default detection, provide your own visibility logic:

Custom Label

Custom Leave URL

Custom Leave Label

Custom Leave Method

The leave form defaults to POST. If your leave endpoint expects a different HTTP method:

Disabling the Banner

[!NOTE]

If your application has a custom impersonation banner registered, remove it when enabling the built-in banner to avoid duplicates. A warning is logged in local environments when both are detected.

Footer

Every panel gets the Northwestern footer, built to the Department Templates 4.0 structure:

• the "Northwestern University" wordmark, linked to northwestern.edu, and your unit's name
• your unit's address, phone, fax and email
• social accounts under "Connect", Northwestern's unless you configure your own
• your own links under "Quick Links", if you add any
• the links the university's Web Style Guide requires, which can't be removed: Building Access, Campus Emergency Information, Careers, Contact Northwestern University, University Policies, Accessibility, Disclaimer, Privacy Statement and Report a Concern

On full pages the footer renders after the layout, through Filament's BODY_END render hook, so it spans the window below the sidebar and the content. On simple pages such as login it renders inside the layout through SIMPLE_LAYOUT_END, below the card.

Unit Information

The footer shows the unit details from the config. The Web Style Guide requires your unit's address, phone, fax (if you have one) and email. A field that resolves to an empty string is hidden. The fax is optional and has no default.

Adding Links

Set footer.links as label => URL pairs. They render under "Quick Links", next to the required links:

Social Accounts

footer.social lists the accounts under "Connect", as network => URL, in display order. It defaults to Northwestern's Facebook, Instagram and YouTube accounts. Set it to [] to hide the section.

The networks are the ones Department Templates 4.0 has icons for: bluesky, facebook, flickr, instagram, linkedin, pinterest, rss, spotify, threads, tiktok, tumblr, vimeo, wordpress, x and youtube. Other keys are skipped.

Deprecated Footer Arguments

->footer() still accepts officeName, officeAddr, officeCity, officePhone, officeEmail, officeFax and links, and they still take precedence over the config. They are deprecated and will be removed in a future major release. Use the config instead. ->footer(enabled:) is not deprecated.

Required Links

The required links live in the Northwestern\FilamentTheme\Footer\RequiredLink enum, so anything else that needs them, such as a text-only mail footer, reads the same list:

Outside a Panel

The <x-northwestern-filament-theme::footer /> component renders the same footer without Filament, auth or the database, so it works on public pages and on error pages that render while the database is down. With no props it renders from the config:

Its office-* and links props mirror the deprecated ->footer() arguments. They still work and are deprecated in the same way.

The footer inlines its own styles, which use the --nu-* custom properties and fonts. Inside a panel those come from the theme CSS; on a page without it, load dist/tokens.css as well (see Tokens Without Filament). The standalone footer is light only.

Disabling the Footer

Pass enabled: false or a closure that returns a boolean:

Date Range Filter

DateRangeFilter builds a table filter with From and To dates, its query and its indicators. Both dates use the browser's own date input: Filament's custom picker nests its input inside a button, which screen readers can't operate and axe reports as a nested interactive control.

By default it compares timestamps from the start of the From day to the end of the To day. Pass mode: DateRangeFilter::ModeDate for a date column. icon, limitUntilToToday, fromLabel, untilLabel, fromField and untilField adjust the fields, and showIndicators: false keeps Filament's default indicator.

Customizing Views

To modify the environment indicator, impersonation banner, or footer markup, publish the views:

This publishes the following templates to resources/views/vendor/northwestern-filament-theme/:

• environment-indicator.blade.php — the environment badge and border
• impersonation-banner.blade.php — the impersonation session banner
• footer.blade.php — the institutional footer
• components/footer.blade.php — the <x-northwestern-filament-theme::footer /> component
• social-icon.blade.php — the "Connect" icons
• wordmark.blade.php — the inline dept 4.0 wordmarks

The required links are not in the published view's control: they come from the RequiredLink enum. A footer.blade.php published from 4.0 keeps working, but it hardcodes the social accounts and ignores footer.links from the config. Re-publish it to pick those up.

External CDN Dependency

This theme loads fonts and the favicon from Northwestern's CDN (common.northwestern.edu/dept/4.0/). The wordmark and footer icons are inline SVG. Your application needs network access to this CDN at runtime. If your environment restricts outbound requests or enforces a strict CSP, allowlist https://common.northwestern.edu.

Akkurat Pro is licensed for central hosting by the university only, so the fonts always load from the CDN and are never bundled into this package.
