Upgrading
This guide covers the upgrade from 1.x to 2.x. Version 2.x exists for filament 4.
The column was rewritten for filament 4: it now ships its own alpine component and renders through filament's dropdown.
Upgrade filament
Please follow the filament upgrade guide first.
Bump the constraint
composer require guava/filament-icon-select-column:"^2.0"
Publish the assets
The column now ships its own JS, so you need to publish the package assets:
php artisan filament:assets
closeOnSelection() is unavailable
The rewrite dropped closeOnSelection(). If you rely on it, stay on 1.x.
