Column Header Actions

You can add actions to the column headers using the ->columnHeaderActions() method. This method accepts an array of actions that will be displayed in each column header.

Basic Example

<?php
use Filament\Actions\Action;

public function kanban(Kanban $kanban): Kanban
{
    return $kanban
        ->model(Task::class)
        ->statusField('status')
        ->columns([
            // Your columns here
        ])
        ->columnHeaderActions([
            Action::make('add_task')
                ->label('Add Task')
                ->icon('heroicon-o-plus')
                ->color('primary')
                ->action(function($arguments) {
                    // $arguments contains the current column status
                    $this->addTaskToColumn($arguments['status']);
                }),
        ]);
}

Using Action Groups

You can also pass ActionGroup to group multiple actions together:

use Filament\Actions\Action;
use Asmit\AdvancedKanban\Actions\ActionGroup;

public function kanban(Kanban $kanban): Kanban
{
    return $kanban
        ->model(Task::class)
        ->statusField('status')
        ->columns([
            // Your columns here
        ])
        ->columnHeaderActions([
            ActionGroup::make([
                Action::make('add_task')
                    ->label('Add Task')
                    ->icon('heroicon-o-plus')
                    ->action(fn($arguments) => $this->addTask($arguments['status'])),
                Action::make('bulk_edit')
                    ->label('Bulk Edit')
                    ->icon('heroicon-o-pencil')
                    ->action(fn($arguments) => $this->bulkEdit($arguments['status'])),
                Action::make('export_column')
                    ->label('Export Column')
                    ->icon('heroicon-o-arrow-down-tray')
                    ->action(fn($arguments) => $this->exportColumn($arguments['status'])),
            ])
            ->label('More Actions')
            ->icon('heroicon-o-ellipsis-vertical')
            ->color('gray'),
        ]);
}

Accessing Column Context

The action callback receives an $arguments array containing:

• status - The current column's status value
• Any additional data you pass to the action

Best Practices

• Use column header actions for operations specific to that column
• Group related actions using ActionGroup for better organization
• Provide clear labels and icons for better user experience
• Consider the column context when designing actions
