Ternary filters

Overview​

Ternary filters allow you to easily create a select filter which has three states - usually true, false and blank. To filter a column named is_admin to be true or false, you may use the ternary filter:

use Filament\Tables\Filters\TernaryFilter;

TernaryFilter::make('is_admin')

Using a ternary filter with a nullable column​

Another common pattern is to use a nullable column. For example, when filtering verified and unverified users using the email_verified_at column, unverified users have a null timestamp in this column. To apply that logic, you may use the nullable() method:

use Filament\Tables\Filters\TernaryFilter;

TernaryFilter::make('email_verified_at')
    ->nullable()

Customizing the column used by a ternary filter​

The column name used to scope the query is the name of the filter. To customize this, you may use the attribute() method:

use Filament\Tables\Filters\TernaryFilter;

TernaryFilter::make('verified')
    ->nullable()
    ->attribute('status_id')

Customizing the ternary filter option labels​

You may customize the labels used for each state of the ternary filter. The true option label can be customized using the trueLabel() method. The false option label can be customized using the falseLabel() method. The blank (default) option label can be customized using the placeholder() method:

use Illuminate\Database\Eloquent\Builder;
use Filament\Tables\Filters\TernaryFilter;

TernaryFilter::make('email_verified_at')
    ->label('Email verification')
    ->nullable()
    ->placeholder('All users')
    ->trueLabel('Verified users')
    ->falseLabel('Not verified users')

Customizing how a ternary filter modifies the query​

You may customize how the query changes for each state of the ternary filter, use the queries() method:

use Illuminate\Database\Eloquent\Builder;
use Filament\Tables\Filters\TernaryFilter;

TernaryFilter::make('email_verified_at')
    ->label('Email verification')
    ->placeholder('All users')
    ->trueLabel('Verified users')
    ->falseLabel('Not verified users')
    ->queries(
        true: fn (Builder $query) => $query->whereNotNull('email_verified_at'),
        false: fn (Builder $query) => $query->whereNull('email_verified_at'),
        blank: fn (Builder $query) => $query, // In this example, we do not want to filter the query when it is blank.
    )

Filtering soft deletable records​

The TrashedFilter can be used to filter soft deleted records. It is a type of ternary filter that is built-in to Filament. You can use it like so:

use Filament\Tables\Filters\TrashedFilter;

TrashedFilter::make()
