Now that we have examined the various Zope 3 components that comprise a theme product, we now need to look at what pieces can be modified through the ZMI. Remember that we are treating stylesheets and images as skin layer objects, so they can be modified the way we discussed in Chapter 5, Making Manual (TTW) Changes or What Not to Do.
As for other components, the short answer is that the following can be customized through the ZMI: any templates that come from the plone.app.layout
and plone.app.portlets
directories, and any browser layer templates that might be in your theme product.
These templates can be customized through the ZMI using a tool known as portal_view_customizations
. This tool is accessible using a URL like the following:
http://localhost:8080/testsite/portal_view_customizations/registrations.html
Specifically, you will want to scroll down on this page to get to the section called zope.interface.Interface
.
