Andreas Weder updated MGNLUI-106:
---------------------------------
Priority: Neutral (was: Major)
Set lower priority as this is more a nice-to-have. I will add a separate issue
to ensure that we do NOT sort trees alphabetically.
> Implement sorting in trees
> --------------------------

> Key: MGNLUI-106
> URL: http://jira.magnolia-cms.com/browse/MGNLUI-106
> Project: Magnolia UI
> Issue Type: Sub-task
> Security Level: Public
> Affects Versions: 5.0 Alpha1
> Reporter: Andreas Weder
> Fix For: 5.0
>
>
> We're currently sorting nodes in the tree view alphabetically. That's also
> how it has been specified. However, I've been notified by Jan that this is
> actually NOT how it should work, since the *manual sort order in the tree is
> very important*. In particular, it can be used to rearrange items in
> navigation menus and to structure the page tree in any way a customer wants.
> But sorting in trees still makes sense. Here's how I've research and devised
> how this could work:
> * for every column except the "Page" or first column, items are sorted
> *within their hierarchy level only* (see below) and depending on the
> value/column type, i.e. alphabetically, by date and time or (e.g. in case of
> the "Status" column) in a pre-defined, more semantical sort order.
> * if you sort by "Page" column, we return to the manual sort order and do not
> show any sort arrow any more (there's no sort direction there anyway)
> Sorting within a single level in the hierarchy is typically how sorting is
> done in trees.
> h2. Details on sorting within a hierarchy level
> Sorting in a hierarchy (or tree) sorts all elements on a particular level
> among themselves and does so on every level. If you e.g. have the following
> tree, sorted by (node) titles, thus alphabetically, and in ascending order:
> {code}
> A
> |--A
> | D
> B
> |--U
> {code}
> ..., if you then reverse the sort direction, you'll get:
> {code}
> B
> |--D
> | A
> A
> |--U
> {code}
> The mechanics shall are the same as if you do sorting in a list: you simply
> click in the column header to sort by the attribute represented by that
> column. Clicking the same header again changes the sort direction.
