I am really confused about these 2 concepts. I am basically wanting to change the appearance of the Joomla category page that lists the sub-categories in it. I dont like the default "Alternative Layout" options of Blog and List type. I want to show the sub-categories with an image + sub-category title style similar to some Portfolio layouts I've seen. So I started googling and reading a few docs on how to do this. During this time, I came across the Layout Overrides in Joomla which says that we can create alternative Joomla Layouts to display Modules, components, Category and Menu Items.
Q1) So does this mean that I can create a new layout (for portfolio category as an example) and if I place them inside "templates/myTemplate/html/com_contact/category" folder this layout option will be listed under Alternative Layout drop-down list in admin panel?
While I was reading some more, I then came across the K2 method where it says that K2 allows creating sub-templates to have different styles for each categories. I havent decided if I am going to use K2 or the core Joomla articles. But my main concern is to style some category pages differently to the default blog or list options. When I read the above article, I thought this can be done in Joomla core itself. But when I read the K2 article on Templating with K2 (and the concepts of sub-templates), it said that the core Joomla doesnt allow sub-templating and K2 can do that.
Q2) What is the difference between creating sub-templates for K2 categories and creating custom template layouts for Joomla categories?
I am totally confused here. If Joomla allows to create different layouts for categories which can then be chosen from the admin panel on what layout to use for that category, what is so special about K2's sub-templating which claims that only K2 allows the flexibility of choosing a different layout for different categories?
Can someone help me understand this please? I have been searching to understand the difference for several hours and I am still stuck on this...
I am new to Joomla and I am using the Joomla version 3.3.
There is a big difference in Joomla core Alternative-Layouts and K2's approach. Hard to explain in theory...
Joomla:
The core feature offers two choices: Either create Alt-Layouts and assign them to each Category and (each!) Article in Backend. Or with a new, alternative MenuItem. The latter is achieved through an additional XML file with same name and location. As long as you work with Categories and Listings, the result is quite similar. But it is different when it comes to the Article Fullview: You won't get an alternative layout for full view automatically! You have to assign the layout in backend or use 1 global setting from the article options. The latter will only apply to articles that have no respective Alt-MenuItem. This can result in a "chicken-egg-situation". AFAIK, frontend submission requires an alternative MenuItem for each edit-form. You can't get an alternative full-view layout when you click on a blog/list item "easily". The links from your category items still lead to the "default" without extra work. In my experience, full-view layouts are displayed in the following setups only:
K2:
The layout folder structure is simpler. All layout files live in the same folder, you just rename that container folder. e.g. products. The inner files keep their default names. This results in an easier and automated "workflow". A layout is assigned to a category and/or its sub-categories. Article full-views pick up their layout automatically, due to the file/folder structure. There is no difference between frontend/backend. No manual assignment on article edit is needed. Nor single K2 items in the menu. (not to mention, that you get extra fields per category)
Hope this helps.
