CKEditor

Deaktivieren

Seiten-TSconfig zum deaktivieren der t3sbootstrap-Konfiguration:

RTE.default.preset = default || minimal || full

Fontawesome

EXT:rte_ckeditor_fontawesome installieren und aktivieren.

Das "statische Template" der EXT:rte_ckeditor_fontawesome darf/sollte nicht eingebunden werden!

Custom CKEditor

Du kannst den CKEditor individuell anpassen. Ein Blick in die EXT:t3sb_package (ab v1.0.1) kann hier weiterhelfen (ext_localconf.php & MyCustomPreset.yaml).
Hier z.B. die Datei MyCustomPreset.yaml mit Tabellen, CodeBlock u.a.:
