I want to add a form where the user in the backend can link a page with multiple other pages. Something like "You might also be interested in..." but NOT dynamically generated.
I found this tutorial:
but the problem is, that when I set a relation the site tree is modified.
What I want is something like:
Frontpage is linked with About page
Contact page is linked with About Page and Imprint

How do I have to modify this code to achieve this?

public static $has_many = array(
    'Boxes' => 'Page'

   public function getCMSFields() {
    $fields = parent::getCMSFields();
    $gridFieldConfig = GridFieldConfig_RelationEditor::create()->addComponents(
         new GridFieldDeleteAction('unlinkrelation')
    $gridField = new GridField("Boxes", "Boxes", $this->Boxes(), $gridFieldConfig);
    $fields->addFieldToTab("Root.Boxes", $gridField);
    return $fields;

With help of this post I'm able to select multiple posts, but the values are not saved and I cannot access them from my template.
How can I save my selection in the database and access them from my template?

I suspect you're trying to assign a $has_many with a corrsponding $has_one relation. Also realitistally what you probably want is for Page to have $many_$many $belong_many_many relation with itself since any page can actually belong to multiple other pages
