Muito obrigado Christian :slight_smile:

It’s really helpful to see how you’ve handled this! To declare the namespace for Barba, are you still doing this (below)?

This is what I’m currently doing: templates/layouts/base.blade.php: ... \<div id="page-wrapper" role="document"\> \<div class="page-container" data-namespace="{!! $current\_template !!}"\> .... \</div\> \</div\> ... src/controller.php: add\_filter( 'sage/template/global/data', function( $data, $template ) { return ['current\_template' =\> basename( $template ,'.blade.php' ),]; }, 10, 2 );
