First we set up a simple structure for your content:
- Consider your web site as a book.
- Your first chapter is about wines, the second chapter about liqueurs (sections).
- The first chapter about wines has two paragraphs (categories), one for red wines, one for white wines.
- Each paragraph contains one or more reviews, i.e. "Beaujolais Nouveau 2008" (content item) in the red wines-category.
Soon you will run into all sorts of issues with this setup, since you will only have two chapters (sections) available for your reviews and lots and lots of reviews (the actual content items or articles) in your paragraphs (categories). You will need more levels (or: a better hierarchy) to organise and seperate your content items.
Let's move the categories up one level:
Make the above mentioned categories a section instead, as shown below:
- Consider your web site as a book.
- Your first chapter is about white wines, the second about red wines, the third about liqueurs (sections).
- The first chapter on red wines has more then 10 paragraphs, one for Garnay grapes, one for Cabernet Sauvignon grapes, one for Merlot grapes and so on (categories).
- Each paragraph contains one or more reviews, so you will get: red wines (sections) > Garnay grapes (categories) > "Beaujolais Nouveau 2008" (content item or article).
Brian suggests to plan your web site on paper first and I couldn't agree more. You need a plan before you start setting up your sections and categories, otherwise you will end up with a time consuming 'trial and error'-project.
At the other hand, as a beginner your don't need to worry too much. As soon as you have added content items in Joomla, you can rearrange them over and over again.
Grab a book and have a look at the index, you might come up with a totally different idea for your sections, categories and articles.
If you only have a limited number of articles, don't create sections and categories and consider to keep these articles 'uncategorised' instead.
Why wait?
