In the past, we used to add metadata to the "add post" section as a featured section, but I can't find the codes now on Google. I will enter posts as ads and add an ad slider. My gallery will be like a gallery slider on the Sahibinden classifieds website. Should I add a gallery upload button to the metadata section in the add post section, and will the uploaded images appear in the slider? Is there anyone knowledgeable about this coding aspect?
