Like with validators, using custom editors is possible as well. Every dataType has it’s default editor set, which can have options applied like:
TYPO3: Neos: userInterface: inspector: dataTypes: 'string': editor: 'TYPO3.Neos/Editors/TextFieldEditor' editorOptions: placeholder: 'This is a placeholder'
On a property level this can be overridden like:
TYPO3: Neos: userInterface: inspector: properties: 'string': editor: 'My.Package/Editors/TextFieldEditor' editorOptions: placeholder: 'This is my custom placeholder'
Namespaces can be registered like this, as with validators:
TYPO3: Neos: userInterface: requireJsPathMapping: 'My.Package/Editors': 'resource://My.Package/Public/Scripts/Inspector/Editors'
Editors should be named <SomeType>Editor and can be referenced by My.Package/Inspector/Editors/MyCustomEditor for example.
Registering specific editors is also possible like this:
