Portlet with call to action

Project description


This shows a call to action: an overlay with an image, titel rich text. This calls the attention of a visitor to take action, usually to click a link or button.


Works on Plone 4.3.x, tested explicitly on Plone 4.3.8. Not yet compatible with Plone 5: the javascript and css need work.


  • A call to action portlet. This is basically a copy of the static text portlet with a few extra options.

  • In the portlet you can set the number of milliseconds before the overlay is shown.

  • When the overlay is shown, a cookie is set. We use this to show the overlay only once. The cookie is specific for this portlet: a new call to action portlet will be shown once too.

  • When you edit the portlet, you can use a checkbox to say that this is not a minor edit, but a new version. The previous cookie is then not valid anymore and the visitor will again see the overlay once.

  • The portlet itself is never shown. Instead a viewlet looks for portlets and shows the contents after a pause. This avoids a portlet column taking up space but not showing anything when there are no other portlets.

  • You can create multiple portlets if you really want to, but only one overlay is shown on a page. If there are three portlets, and the user has already seen the first one but not the others, then the second one will be shown.


This add-on is planned to be used on and, who have sponsored development, but the sites may not always have a call to action configured.
