asCpScreen controller method - allow removing form from page completly

[piotrpog]

asCpScreen is a great method in craft control panel controllers. It allows us to define things like breadcrumbs or page title with chaining methods, instead of awkwardly declaring Twig variables in templates.

The problem is, that every page using this method has its contents enclosed in the form which can be submitted. Would be great if we could just get rid of this form and use asCpScreen for things like listing pages.

Just found out that this can be done by setting ->action() method to false.

It should be null by default, which would prevent it from being a form on full pages, however slideouts will still assume it should be a <form> so that’s something we should address in Craft 5.

(Finally) made it possible to create non-form slideouts, for Craft 5.8 (2f925b3).

To do it, you’ll need to include containerElement: 'div' in the settings object.

const slideout = new Craft.CpScreenSlideout('my/render/action',
  containerElement: 'div',
});

When containerElement isn’t 'form' (still the default), the slideout won’t get a “Save” button, and the close button will be labelled “Close” instead of “Cancel”.
