By default when I type in sitename/blog I get all the articles with the category of blog. I would like to be able to filter this list by the tags associated with each blog item but I cannot find how to do this.
I can see how I can use modules to display but i want the actual component to be filtered. Could someone please tell me how this can be achieved ?
Joomla Content component does not provide a way to filter by fixed tags in a menu item.
You can implement an extension for extended tags options. For example, K2 does have: Tag Create a menu item linking to a tag in K2.
