= SliceGroup =

A slice of type SliceGroup will display a group of slices[[BR]]
The members of the group are determined using their tags, the slice group will display each slice which has the specified tag.[[BR]]
This is one of the most powerful features of ACR and can be used to implement News, Image Galleries, Video Repositories, etc...[[BR]]
The slice group also implements pagination, you can specify how many slices to view for each page.

Not implemented

== Use ==

 * view: '''slicegroup'''

 * content: '''ini'''

== INI ==

Starts with a '''[group]''' section and must contain the following variables

 * '''filter_tag''' = the tag for which to filter the group, slices with this tag will be displayed by the slicegroup

The following variables are optional

 * '''size''' = how many slices to see inside each slicegroup page, default is 0 which means ''unlimited''

 * '''type''' = which tag to use to embedd the displayed slices. By default each slice is embedded inside a ''div'', you can specify ''li'' for example to apply things like jQuery Carousel to the slice gorup

 * '''preview''' = Whenever to display the slice itself or the preview of the slice for each slicegroup member (1 means display preview, 0 means display slice)

 * '''orderer''' = Which ordering function to use to display the members of the slicegroup. By default they are not ordered. The ''content_time'' ordering function is the only one available by default. You can register new ordering functions by appending them to the ''acr.lib.views.SliceGroupRenderer.slice_orderers'' dictionary (key is the name of the orderer, values is the callable). The argument passed to the ordering function is the SQLAlchemy query to modify.

== Example ==

{{{
[group]
filter_tag=news
size=5
orderer=content_time
preview=1
}}}
