Bearbeiten von „ProcessWire - Layout Blöcke mit RepeaterMatrix“

Mit einer RepeaterMatrix, kann man Einzelfelder zu Gruppen zusammenfassen um z.B. verschiedene Layoutblöcke zu definieren. Diese Gruppen kann man wiederholt nutzen. Im Gegensatz zum Repeater Feld können nicht nur gleichartige Felder wiederholt werden. Der Benutzer kann alle in der Matrix definierten Gruppen auswählen.

== Quickstart ==

* ProFields: Repeater Matrix installieren 
* Felder definieren die man später in den Gruppen nutzen möchte
* Ein RepeaterMatrix Feld definieren und dort dann die Gestaltungsblöcke definieren.

=== Kurzversion layout_blocks.php ===
Integriert die layout_blocks.inc ins Template und verkürzt diese. Vorteil: übersichtlich. Nachteil: nicht so schön zu debuggen. Muß noch getestet werden.
