Filament: ToggleColumn: Only One Active Record (Set Others to False)

All you need to do is use the function beforeStateUpdated() on the ToggleColumn and run one update Eloquent query inside.

For example, if you have a DB column users.active as boolean, here's the code:

app/Filament/Resources/UserResource.php:

public static function table(Table $table): Table
{
    return $table
        ->columns([
            Tables\Columns\TextColumn::make('name'),
            Tables\Columns\ToggleColumn::make('active')
                ->beforeStateUpdated(function (User $record) {
                    User::where('id', '!=', $record->id)->update(['active' => false]);
                }),
        ])

The table will refresh automatically.
