Hi @justin.thanh84v20, thanks for reaching out. Can you describe a little further what you are looking for specifically? Would you like to be able to remix an app that can produce cloned columns like mine? Or do you need a custom list viewer for your purposes? (if you copy my app, yours will only appear as mine do unless you change the components and code. However, you can use the same style and fill it in with your info. You should be able to add/delete components inside a ‘sample’ column to make your style and follow a pattern based on the component number to be able to populate any other element that you set inside the original sample column.
I have previously shared that here.
Is there a different use case than what is shown in that link?
