Navigator

A simple object list is good for small lists, but not very efficient if we have many objects in a folder. We would then like to break up the list and for example only show the 10 latest objects and have navigation possibilities to see the other objects. The navigator itself is just a template we include that takes some parameters.

Example:

{let numberOfObjects=10}

{let articleCount=fetch( 'content', 'list_count',

                        hash( 'parent_node_id', $node.node_id ) )}

{let articleList=fetch( 'content', 'list', hash( 'parent_node_id', $node.node_id,

                                                'sort_by', $node.sort_array,

                                                'offset', $view_parameters.offset,

                                                'limit', $numberOfObjects ) )}

{section name=articleLoop loop=$articleList}

   {node_view_gui view=element content_node=$articleLoop:item}

{/section}

{include name=navigator

        uri='design:navigator/google.tpl'

        page_uri=concat( '/content/view/full/', $node.node_id, '/' )

        item_count=$articleCount

        view_parameters=$view_parameters

        item_limit=$numberOfObjects}

{/let}

{/let}

{/let}

As you can see, we do two fetches. First we fetch the total number of objects on the current position in the tree. Next we fetch only 10 articles and print these as normal. In the end of the list we will make the navigator. This is done by including one of the navigator templates (or by creating a new one). Two navigator templates are supplied, templates/navigator/simple.tpl and templates/navigator/google.tpl. simple.tpl is, as the name says, a very simple navigator you can use as an example to build your own, and google.tpl is a navigator with a design inspired by Google.

The navigator takes several parameters:
