Select filters
Overview
Often, you will want to use a select field instead of a checkbox. This is especially true when you want to filter a column based on a set of pre-defined options that the user can choose from. To do this, you can create a filter using the SelectFilter
class:
use Filament\Tables\Filters\SelectFilter;
SelectFilter::make('status')
->options([
'draft' => 'Draft',
'reviewing' => 'Reviewing',
'published' => 'Published',
])
The options()
that are passed to the filter are the same as those that are passed to the select field.
Customizing the column used by a select filter
Select filters do not require a custom query()
method. 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\SelectFilter;
SelectFilter::make('status')
->options([
'draft' => 'Draft',
'reviewing' => 'Reviewing',
'published' => 'Published',
])
->attribute('status_id')
Multi-select filters
These allow the user to select multiple options to apply the filter to their table. For example, a status filter may present the user with a few status options to pick from and filter the table using. When the user selects multiple options, the table will be filtered to show records that match any of the selected options. You can enable this behaviour using the multiple()
method:
use Filament\Tables\Filters\SelectFilter;
SelectFilter::make('status')
->multiple()
->options([
'draft' => 'Draft',
'reviewing' => 'Reviewing',
'published' => 'Published',
])
Relationship select filters
Select filters are also able to automatically populate themselves based on a relationship. For example, if your table has a author
relationship with a name
column, you may use relationship()
to filter the records belonging to an author:
use Filament\Tables\Filters\SelectFilter;
SelectFilter::make('author')
->relationship('author', 'name')
Preloading the select filter relationship options
If you'd like to populate the searchable options from the database when the page is loaded, instead of when the user searches, you can use the preload()
method:
use Filament\Tables\Filters\SelectFilter;
SelectFilter::make('author')
->relationship('author', 'name')
->searchable()
->preload()
Customizing the select filter relationship query
You may customize the database query that retrieves options using the third parameter of the relationship()
method:
use Filament\Tables\Filters\SelectFilter;
use Illuminate\Database\Eloquent\Builder;
SelectFilter::make('author')
->relationship('author', 'name', fn (Builder $query) => $query->withTrashed())
Searching select filter options
You may enable a search input to allow easier access to many options, using the searchable()
method:
use Filament\Tables\Filters\SelectFilter;
SelectFilter::make('author')
->relationship('author', 'name')
->searchable()
Disable placeholder selection
You can prevent the placeholder (null option) from being selected using the selectablePlaceholder()
method:
use Filament\Tables\Filters\SelectFilter;
SelectFilter::make('status')
->options([
'draft' => 'Draft',
'reviewing' => 'Reviewing',
'published' => 'Published',
])
->default('draft')
->selectablePlaceholder(false)
