Einrückungen im Sorting mode 5 pagetree

[Samson1964]

Wie bekomme ich denn die Einrückungen im sorting mode 5 richtig hin?

"Aktuelle Berichte" (Ebene 0) und "Deutsche Jugendmeisterschaften" (Ebene 1) sieht noch okay aus. Darunter "Einzel" und "Ländermeisterschaften" ist aber bereits Ebene 2. "EU-Meisterschaften" und "Europacup für Vereinsmannschaften" ist aber wieder Ebene 1, sieht aber wie 0 aus.
Fast beschleicht mich das Gefühl, nur die Einträge mit dem Toggle-Icon (+ -) stehen richtig. Die ohne Icon müßten um die Icongröße weiter rechts eingerückt werden. Habe ich irgendein Blind-Icon übersehen? Hier der DCA:

Ich habe jetzt mal weitergeforscht.
Die Anzeige des Standardicons scheint nicht die richtigen Abstände zu verwenden. Ich sah mir deshalb genauer den label_callback in tl_page an. Und mit der Verwendung eines eigenen Icons klappt es jetzt:



Jetzt bastele ich dann weiter an der Breadcrumb-Navigation, wie man sieht.

    }
} 

Die Breadcrumb-Funktion habe ich für Nachahmer mal drin gelassen. Dort baue ich die Datenbankabfragen ein, um die Breadcrumb aufzubauen.
