This package provides theme selection for Lineage subsites.

In Plone we have (aka Diazo theming) and the old CMF skins. Both are almost independent.

lineage.themeselection adds a lineage.registry local component containing the settings for the based theme. An object tab appears for site-managers to configure the subsite theme.

Additionally it adds a schema-extender to the ChildSite Folder adding a CMFSkin selection dropown to the settings tab under edit.

On traversal skin is switched and a plone.browserlayer marker is put on the request.


  • add the egg to your buildouts eggs-section.
  • apply the GS-profile to your Plone site.


Open the "Theme" tab on your ChildSite and edit the Diazo theme and the theme base skin.


Just depend in your buildout on the egg lineage.themeselection. ZCML is loaded automagically with z3c.autoinclude.

Install it as an addon in Plone control-panel or portal_setup.

This package is written for Plone 4.1 or later.
