How can I exclude some special "portfolio categories" from the "sortable portfolio overview page"?
I mean not the images (they should be shown), but only the small words of those special categories, with which we can sort the portfolio items at their overview page.
Here: the words "verkauft", "verfügbar" (= portfolio categories) should not appear at this overview, but the images, tagged with this categories should remain there!
Explanation: I tag images with, for example, "Acryl" + "verkauft" and show at the portfolio single page a status "sold".
"Sold" is set as a portfolio category.
But this category has the only aim, to show me the status at the portfolio single view,
and the (portfolio category) word "sold" should not appear on the portfolio overview page, but images tagged with it, should remain.
