My goal is it to change the layout of my front page which is a menu item of the type 'tag list' (or something similar, don't know the precise translation). As usual, I made a file overriding the view template which creates the respective section.
So I've made a file
<template>/html/com_tags/tag/default_items.php with the same contents as
components/com_tags/views/tag/tmpl/default_items.php, expecting to see any changes I make to the aforementioned file. However, even if I empty the file, the result is the same as without the file alltogether.
EDIT - UPDATE 1: As suggested in an answer, I have tried creating an alternative layout instead. So I made the file
<template>/html/com_tags/tag/custom_layout_test.php and put a test string in it, but I cannot select it in the admin interface's
template style option of the menu entry.
I just asked Google 'joomla tag list override' and it told me: http://forum.joomla.org/viewtopic.php?f=706&t=854545
Edit - Update 1:
components/com_tags/views/tag/tmpl/default.php and rename it to
components/com_tags/views/tag/tmpl/default_items.php and edit it to your liking.
Then you should set alternative tag list layout 'namewithoutunderscores' as default in Tagged Items Options.
