Allows to show or hide the left or right portlet column per document

Project Description

What does it do?

This Plone addon allows editors to control the visibility of portlet columns - no matter if they are empty or contain portlets.

Editors can choose between:

  • showing a column (even if it does not contain any portlets)
  • hiding a column (even if it contains portlets)
  • only show non-empty columns (standard Plone behaviour)

How does it work?

wm.showhidecolumns uses infrastructure available in Plone 4:

the request variables disable_plone.rightcolumn and disable_plone.leftcolumn are used to control the column visibilty. (no portletmanagers get overwritten or monkey-patched).

archetypes.schemaextender is used to make the settings available on all types implementing wm.showhidecolumns.interfaces.IControlColumns

plone.browserlayer is used to make sure the extra fields and the viewlet that adds the request variables only show up if the product is installed.

How do I use it?

To allow control column visibilty on custom content types just make them implement wm.showhidecolumns.interfaces.IControlColumns.

How can I help?
