Hi, yurivisser!
In order to have different colour schemes for every menu-item, you can do the followings:
1. Login into your Joomla Admin
2. Goto Modules Manager and click on JA News 1.3.0 name and you will see Group by Category or Section and Category (Section) ID parameters
example: I select Group by Category or Section is Section.
3. At Category (Section) ID parameter, you can customization colour schemes for menu item by edit:
<blockquote>5:red
8:green
6:orange12:cyan
9: pink
11:lime</blockquote>
Syntax for this is: <ID>:<color>. ID can be sectionID or categoryID base on what you choose right above and color can be color English name in this list (red, cyan, deepblue, green, orange, pink, lime))
hope to help for you! 🙂
