Using Neos & Flow
#1

Hey there,
I’m trying to add font colors to the “Neos.Neos/Inspector/Editors/RichTextEditor”. Poorly I absolutly can’t figure out how to do this. Somebody got a hint for me?

font_color_hint

      ui:
        label: 'Toggle the editor'
        inspector:
          group: page
          editor: 'Neos.Neos/Inspector/Editors/RichTextEditor'
          editorOptions:
            placeholder: '<p>placeholder</p>'
            autoparagraph: true
            linking:
              anchor: true
              title: true
              relNofollow: true
              targetBlank: true
            formatting:
              strong: true
              em: true
              u: true
              sub: true
              sup: true
              del: true
              p: true
              h1: true
              h2: true
              h3: true
              h4: true
              h5: true
              h6: true
              pre: true
              underline: true
              strikethrough: true
              removeFormat: true
              left: true
              right: true

I can’t tell you how to do it as I didn’t customize CKEditor yet, but maybe I can give you a starting point.
Here is the documentation from Neos for extending the CKEditor 5 which is what you are trying to do. And here is the documentation from CKEditor themselves. Somebody else also tried that and had a few problems, so maybe you can learn from them too
