Install

Managed edition

When using the managed edition it's pretty simple to install the package. Just search for the package in the Contao Manager and install it. Alternatively you can use the CLI.

# Using the contao manager
$ php contao-manager.phar.php composer require contao-bootstrap/accordion~2.0

# Using composer directly
$ php composer.phar require contao-bootstrap/accordion~2.0

Symfony application

If you use Contao in a symfony application without contao/manager-bundle, you have to register following bundles manually:

class AppKernel
{
    public function registerBundles()
    {
        $bundles = [
            // ...
            new \ContaoCommunityAlliance\MetaPalettes\CcaMetaPalettesBundle(),
            new Netzmacht\Contao\Toolkit\Bundle\NetzmachtContaoToolkitBundle(),
            new ContaoBootstrap\Core\ContaoBootstrapCoreBundle(),
            new ContaoBootstrap\Grid\ContaoBootstrapAccordionBundle()
        ];
    }
}

Migration

To automatically migrate your accordion from Start- and Stop-Wrappers to nested fragments, you have to enable the migration by creating config/packages/contao_bootstrap_accordion.yaml with the following content:

contao_bootstrap_accordion:
    enable_wrapper_migration: true

Afterwards you can run the migration in the Contao Manager or via CLI.

Deprecated

The legacy content elements bs_accordion_start, bs_accordion_end, bs_accordion_group_start and bs_accordion_group_end are deprecated and will be removed in a future major version. Use bs_accordion_wrapper and bs_accordion_group_wrapper instead.

To disable the legacy elements now, set the following configuration:

contao_bootstrap_accordion:
    enable_legacy_elements: false
