Getting scala's template loop index in playframework

I am trying to iterate in a playframework view, but without success for now. I have the following structure:

@if(list != null) {
    for(a <- 0 to list.size()/5)
    {
       //  some html, where I want to get the value of a
       for(b <- a*5 to a*5+5)  // here I want to use the a value again
       {
            some html
       }
    }

So my question is how to get the current index of the loop so that I will be able to use it.

You should combine it in one for loop: 

@if(list != null) {
    @for{a <- 0 to list.size()/5
        b <- a*5 to a*5+5}
            yield html
    }
}

And use option instead of null checking. Also you can use map function to transform your list. See details in Play documentation - http://www.playframework.com/documentation/2.0/ScalaTemplates
