Hi guys, I'm searching a way to edit the default Item menu and organyze it in pages. For example, if I have less than 8 item I can see them in a single page with a single column, otherwise the first 8 items will be shown in the first page an the other items in the other pages (with Q/W or LEFT/RIGHT I can navigate through the pages and each page can have only 8 items).

I hope that it's clear 😅 it would be possible to do this?

Thanks in advance

Are you using any custom item scene script?

Just one column, just 8 item per page, no vertical scrolling and Q/W or LEFT/RIGHT to navigate through the pages.

Well here's a quick 'n dirty solution. It is exactly as you requested without any extra bells and whistles.
