Beispiel
Verwendung
Verwenden Sie die Textarea-Komponente wenn die Eingabe von größeren Textmengen erforderlich ist, z.B. bei der Erfassung eines Anliegens innerhalb eines Formulars. Mit Hilfe des Attributs _rows kann die Höhe der Textarea in Zeilen bestimmt werden. Über das Attribut _resize kann zusätzlich festgelegt werden ob und in welche Richtung die Textarea vergrößert werden kann. Der Wert none sperrt die Textarea gegen Größenänderungen.
