List Pages in a Category by Letter
If you look at http://doc.tiki.org/Unified-Index you’ll see that the title_initial and title_firstword so you can use them.
In my case I needed to filter them so: http://doc.tiki.org/PluginList-filter-control-block#Tracker_items_title_that_start_with_the_letter_B
Now it may be a bit tedious but at least you can use 26 plugin List to filter by letter and organise them. ?
That's actually the best idea I had come up with too - in lieu of Tiki not having a built-in feature to display pages like this, I am planning on building a template with a list plugin for each letter - that way I only have to change the category. Just to make sure, this is along the lines of what you're talking about right?
{LIST()}
{filter type="wiki page" categories=1}
{filter field="title_initial" exact="A"}
{LIST
