Looks like you’re half way there already! Now I know what you’re doing it probably does make sense to set the classes via TV.
Your rowTpl looks fine. What you need to do is create a new TV called
menuLiStyle - if you haven’t already. Set the input type to Radio Button or DropDown List depending on your preference, then drop the following in the ’input option values’ box:
Blue==blue||Green==green||Orange==orange
Drop
Blue==blue into the default values box.
This will set a class of either ’blue’, ’green’ or ’orange’ to each <li>. Obviously change orange to whatever colour your forum button is. You can leave the upper case colours as is, or change them to a more appropriate name if need be.
If you don’t want blue to show, just set an output filter on the TV like this:
[[+tv.menuLiStyle:is=`blue`:hide]]
