Sulu as a Pagebuilder: block within block

Question

I want to use sulu as a pagebuilder. A have a block with multiple elements in it. Now my next goal is to provide fields to sho a "Accordion-Script".

The Elements consist of

• title (text_line)
• content (text_editor)

I hoped that i could use a block in an other block like so:

<block name="contents"
           default-type="editor"
           minOccurs="0"
           maxOccurs="200"
           mandatory="true">
        <meta>
            <title lang="de">Artikelinhalt</title>
            <title lang="en">Contents</title>
        </meta>
        <types>
            <type name="tabs">
                <meta>
                    <title lang="de">Tabs</title>
                    <title lang="en">Tabs</title>
                </meta>
                <properties>
                    <block name="tabContents"
                           default-type="editor"
                           minOccurs="0"
                           maxOccurs="200"
                           mandatory="true">
                        <types>
                            <type name="tabContent">
                                <meta>
                                    <title lang="de">Texteditor</title>
                                    <title lang="en">Text editor</title>
                                </meta>
                                <properties>
                                    <property name="article" type="text_editor">
                                        <meta>
                                            <title lang="de">Inhalt</title>
                                            <title lang="en">Content</title>
                                        </meta>
                                        <params>
                                            <param name="table" value="true"/>
                                            <param name="link" value="true"/>
                                            <param name="paste_from_word" value="true"/>
                                            <param name="height" value="400"/>
                                            <param name="max_height" value="2000"/>
                                            <!-- CKEditor Parameters examples: -->
                                            <param name="extra_allowed_content" value="img(*)[*]; span(*)[*]; div(*)[*]; iframe(*)[*]; script(*)[*]" />
                                        </params>
                                    </property>
                                </properties>
                            </type>
                        </types>
                    </block>
                </properties>
            </type>

[...] here are my other type-attributes.

It does not work (backend is not loading the edit-page at all). Is there a way to do that?

The Page should later be editable by the user and could have a structure like that:

- block
    - text
    - accordion
        - text
        - text
        - text
     - image
