Table of Contents
collective.cover is a package that allows the creation of elaborate covers
for website homepages, especially for news portals, government sites and
intranets that require more resources than a simple page or collection can
offer. However, despite offering rich resources to build a cover,
collective.cover also provides a very easy mechanism for managing its
contents, built around a drag-and-drop interface.
For impatient types, there is a demo installation of collective.cover on Heroku. It needs about 60 seconds to spin up and it will purge all changes after about an hour of non-usage.
Suppose you are running The Planet, a news portal that has a bunch of editors focused on getting news on different topics, like Economy, Health or Sports.
If you are the main publisher of the site, you may want to delegate the construction of the front page of the Economy section to the people working on that content area, but you might not want them messing around the Sports section as well.
Also, suppose you have the final game of the World Cup and the match is going to be defined on penalties: you may want to prepare a couple of cover pages and publish the right one focused on the team that won in the end.
These are the kind of issues we want to solve with this package; we are still far from it, but that is the idea.
These are some of the sites using
- CartaCapital (BR)
- Clean Clothes Campaign (NL)
- Conselho Federal de Administração (BR)
- La Jornada (MX)
- Palácio do Planalto (BR)
- Portal Brasil (BR)
- Rede Brasil Atual (BR)
- Venezolana de Televisión (VE)

- Versioning creates zillions of empty blob files.
If you're using this feature in your site you have to take special attention to the number of free inodes in your file system,
as you can run out of them;
df -icommand to check it.
- Package is not compatible with standard Plone tiles. This will be addressed in a future release, if we get an sponsor.
- AJAX responses are wrapped after installing the package. This was an issue in Blocks that is already fixed; we haven't merge it yet because it will break compatibility with Plone 4.2.
- Not compatible with jQuery 1.9. There is work being done to solve this and to fix plone.app.jquerytools also. We only support jQuery 1.7 and jQuery 1.8 at this time.
See the complete list of bugs on GitHub.
We are currently working on the documentation of the package; this is what we have right now (contributions are always welcomed):
To enable this package in a buildout-based installation:
Edit your buildout.cfg and add add the following to it:
[buildout] ... eggs = collective.cover [versions] ... collective.js.bootstrap = 18.104.22.168 plone.app.blocks = 2.2.0 plone.app.tiles = 1.0.1
If you are using Plone 4.2.x you need to add the following also:
[versions] collective.js.jqueryui = 22.214.171.124 plone.app.jquery = 1.7.2 plone.app.jquerytools = 1.5.7 plone.app.z3cform = 0.6.3 plone.directives.form = 1.1
If you want to use a newer release of
collective.js.bootstrap, you will need to update
[versions] plone.app.jquery = 1.8.3
After updating the configuration you need to run ''bin/buildout'', which will take care of updating your system.
Go to the 'Site Setup' page in a Plone site and click on the 'Add-ons' link.
Check the box next to
collective.cover and click the 'Activate' button.
You may have to empty your browser cache and save your resource registries in order to see the effects of the product installation.
Over the years there have been some packages designed to solve the problem of creating section covers in Plone. We have used and have taken ideas from the following:
- Very old; the legacy code is so complex that is not maintainable anymore. It has (arguably) the best user interface of all. Layouts can not be created TTW. Viewlets are just page templates associated with content types; you can drag&drop viewlets around the layout. Publishers love it.
- Code is very old, but still maintained (at least works in Plone 4). Allows to create complex layouts TTW and use any layout as a template. Easy to extend and edit (but is terrible to find a content to use). Needs a lot of memory to work and aggressive cache settings.
- Allows the creation of layouts TTW but it has (arguably) the worst user interface of all. It is easily extended and there are several add-ons available that provide new functionality for it.
- Home Page Editor of the Brazilian Chamber of Deputies Site
- Strongly based on Collage, this package was presented at the World Plone Day 2012 Brasilia. It allows editing of home pages and the definition of permissions on blocks of content. Works under Plone 3 only.
- A new package that lets site editors add portlets to a set of new
locations: above and below page contents, portal top and footer. The
package comes with a number of flexible layouts that are used to position
the portlets, and locations can be fixed to the nearest site object, to
facilitate inheritance. In
collective.cover(this package), we don't want to use portlets at all.
