Sorry for my misunderstanding, I thought there should be a custom post type called portfolio for projects. So works item is just a gallery format post, isn’t it? And most of all, the way posts are displayed is not customizable, I mean, page builder is avalable just for pages not for posts.
Another quick question to ask you. If I’m not wrong, BM slider is just for posts, i I want to display a full screen slider with custom images, text and link I’m supposed to use Revolution Slider. Right?
