Multiple Zope objects can be combined to form complex web pages. DTML Methods contain chunks of content. Web pages can insert content from DTML Methods. You can recover from mistakes with Undo.

You can programmatically build web pages with groups of objects by looping over them and inserting them. <dtml-in> iterates over a list of objects. <dtml-var sequence-item> inserts the current object when looping over a list of objects. You can get the contents of a folder by calling its object. Values method.

Images can display themselves and can also provide useful information such as size, title, and URL. Get the contents of a Folder with the object. Values method. Get the size of an Image with the get. Size method. Get the URL of an object with the absolute_url method.

You can use forms to pass information between Zope objects. You can programmatically create new Zope objects. Zope documents can be the action of HTML forms.
