On the Laravel News site there's a tutorial posted showing you how to use Blade's View::first functionality to dynamically show a template if it exists.

When building dynamic components or pages sometimes we want to display a custom template if it exists or otherwise fall back on a default one.

[...] We can solve this problem with a series of conditionals or by using view()->exists() to check if a custom template exists or not, however, Laravel 5.5 brings us a better and more elegant way.

A screencast of the functionality in action is included as well as a text-only version with code samples showing the previously used "if view exists" check and the refactor to use View::first instead.

This dynamic view loading feature was added to Blade in Laravel v5.5 and is a great way of keeping your controllers simple by avoiding extra conditionals when dealing with dynamic templates.
