Customizing the page titles

Changing the default title for a specific page

By default, each page has a default title based on both page location and resource name. If you're not happy with the preset title for a specific page and would like to customize it, you can easily change it using Twig Hooks.

Search for "title_block" in the call graph of the Symfony debug profiler in the Twig Hooks section.

We're going to reuse this hook and its template in our config file and add a header key:

config/packages/sylius_bootstrap_admin_ui.yaml

# ...
sylius_twig_hooks:
    hooks:
        # ...
        'sylius_admin.speaker.index.content.header.title_block': # The speaker index title block
            title:
                template: '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig'
                configuration:
                    title: app.ui.browsing_speakers # here is our title override

config/packages/sylius_bootstrap_admin_ui.php

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
    // ...
    $containerConfigurator->extension('sylius_twig_hooks', [
        'hooks' => [
            // The speaker index title block
            'sylius_admin.speaker.index.content.header.title_block' => [
                'title' => [
                    'template' => '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig',
                    'configuration' => [
                        'title' => 'app.ui.browsing_speakers' // here is our title override 
                    ],
                ],
            ],
        ],        
    ]);
};

Note that you can also use Symfony Expression Language in the configuration key for dynamic titles:

config/packages/sylius_bootstrap_admin_ui.yaml

# ...
sylius_twig_hooks:
    hooks:
        # ...
        'sylius_admin.book.show.content.header.title_block': # The show page title block
            title:
                template: '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig'
                configuration:
                    title: '@=_context.book.getTitle()' # Use the current book title

config/packages/sylius_bootstrap_admin_ui.php

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
    // ...
    $containerConfigurator->extension('sylius_twig_hooks', [
        'hooks' => [
            // The show page title block
            'sylius_admin.book.show.content.header.title_block' => [
                'title' => [
                    'template' => '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig',
                    'configuration' => [
                        'title' => '@=_context.book.getTitle()' // Use the current book title
                    ],
                ],
            ],
        ],        
    ]);
};

@=_context contains all the current Twig vars.

Adding an icon

To add an icon to the page title, you need to use Twig hooks configuration.

Search for "title_block" in the call graph of the Symfony debug profiler in the Twig Hooks section. We're going to reuse this hook and its template in our config file.

Here's an example to define a "users" icon on a speaker list.

config/packages/sylius_bootstrap_admin_ui.yaml

# ...
sylius_twig_hooks:
    hooks:
        # ...
        'sylius_admin.speaker.index.content.header.title_block':
            title:
                # We need to reuse the same template as 'sylius_admin.common.index.content.header.title_block'
                template: '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig'
                configuration:
                    icon: tabler:users # You can use any icon from Symfony UX icons.

config/packages/sylius_bootstrap_admin_ui.php

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
    // ...
    $containerConfigurator->extension('sylius_twig_hooks', [
        'hooks' => [
            'sylius_admin.speaker.index.content.header.title_block' => [
                'title' => [
                    // # We need to reuse the same template as 'sylius_admin.common.index.content.header.title_block'
                    'template' => '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig',
                    'configuration' => [
                        'icon' => 'tabler:users' // You can use any icon from Symfony UX icons.
                    ],
                ],
            ],
        ],        
    ]);
};

You can also define a default icon for every "index" pages.

config/packages/sylius_bootstrap_admin_ui.yaml

# ...
sylius_twig_hooks:
    hooks:
        # ...
        'sylius_admin.common.index.content.header.title_block':
            title:
                configuration:
                    icon: tabler:list-details

config/packages/sylius_bootstrap_admin_ui.php

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
    // ...
    $containerConfigurator->extension('sylius_twig_hooks', [
        'hooks' => [
            'sylius_admin.common.index.content.header.title_block' => [
                'title' => [
                    'configuration' => [
                        'icon' => 'list-details'
                    ],
                ],
            ],
        ],        
    ]);
};

Adding a subheader

To add a subheader to the page title, you need to use Twig hooks configuration.

See the previous section to see how to search for the title block.

Here's an example to define a subheader on a speaker list.

config/packages/sylius_bootstrap_admin_ui.yaml

# ...
sylius_twig_hooks:
    hooks:
        # ...
        'sylius_admin.speaker.index.content.header.title_block':
            title:
                # We need to reuse the same template as 'sylius_admin.common.index.content.header.title_block'
                template: '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig'
                configuration:
                    subheader: app.ui.managing_your_speakers # You also need to add this key to your translations.

config/packages/sylius_bootstrap_admin_ui.php

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
    // ...
    $containerConfigurator->extension('sylius_twig_hooks', [
        'hooks' => [
            'sylius_admin.speaker.index.content.header.title_block' => [
                'title' => [
                    // We need to reuse the same template as 'sylius_admin.common.index.content.header.title_block'
                    'template' => '@SyliusBootstrapAdminUi/shared/crud/common/content/header/title_block/title.html.twig',
                    'configuration' => [
                        'subheader' => 'app.ui.managing_your_speakers' // You also need to add this key to your translations.
                    ],
                ],
            ],
        ],        
    ]);
};
