Possible to add non input fields into custom line items ?
My question is related to a previous one here (http://www.drupalcommerce.org/questions/7066/how-display-image-between-c...)
I post it again because now it turns to be more abstract. I mean I asked first about just how to insert a 'displaying' image in the middle of others input fields inside some customized line items, but this question could be more usefull if asking more shortly 'how to add non input fields in custom line items?'
As far as I understand 'custom line item' it seems to be exclusively about grouping 'input' fields inside the, for example, 'Shopping cart form'.
I hope I'm wrong! But cannot find a way of doing this.
How helpful beign able to add between input fields embeded inside custom line items, some images, texts or php codes....
Thank you for any comments on this.
