# Sirius – Provide Custom Cell Editors

## Sirius Semantic Properties View

You can override the default CellEditors in the Sirius semantic properties views by implementing `org.eclipse.sirius.ext.emf.ui.ICellEditorProvider` and provide it through the `org.eclipse.sirius.ui.siriuspropertiescelleditor` extension point.

The semantic properties view

## Other Editors Properties View

This extension mechanism can also be used for other editors properties view. That can be done by providing the `org.eclipse.sirius.ui.tools.api.properties.SiriusExtensiblePropertySource` instead of the default EMF one by replacing the `propertySourceProvider` in the generated editor.
