A viewlet displaying links to subdocuments and quickly loading their content via jquery

Project description


This is a simple add-on that provides a tabbed-style display for the content of documents. You only need to add class “linkcollection” to a h2 heading. This heading will be turned into the title of the tab, and the following content, until the next such heading or the end of the page, will become the tab content. There can only be one tab open at a time - clicking on one tab closes the others.

At the bottom of each tab’s content, an anchor link to the top is inserted. Clicking on it will cause a smooth scroll to the top.

WYSIWYG editor integration

You can add a style to the editor of your choice, so that a heading can be added to a link collection without the need for manually adding a class.

For TinyMCE, go to portal_tinymce/@@tinymce-controlpanel and add the following line under Styles:


For CKEditor, go to @@ckeditor-controlpanel and add the following line under Menu Styles, in the section Block Styles:

{ name : 'Linkcollection', element: 'h2', attributes: {'class': 'linkcollection' } },

Legacy implementation

The first version of the link collection worked by selecting references to documents to be displayed. Hence the name “link collection”. The tabbed collection itself was displayed in a viewlet. The code for this version is still present, but not recommended to use for SEO reasons (content duplication is considered bad).
