Ok, I understand.
So, I stay on 1.9, waiting for your solution.
But wouldn't it be better if there was just the ability to write the URL by hand, without you putting any items id other ways in which you put the URL automatically?
In a company, on a company's WEB site, the Portfolio represents the work that the company has done, so it is certain that it is better that it is indexed by search engines. For this, it should be mandatory to write the URL by hand or, if anything, it is automatically created from the title of the element, as Joomla does, so without item id or anything else which then makes it useless to list the jobs that have been done to be searched on Google through, in fact, these references.
Was I able to explain myself well?
