Inventory Slots
When creating a new shop menu, you'll have to specify certain slot numbers. These numbers may seem random at first, but there's quite a bit of logic behind them. Take a look at this picture:
As you can see, every slot has a unique number. Keep in mind that you cannot use id 36 and 44, as those are used for the navigation betweens pages.
If you add a number higher than 26, it will automatically put it on the next page. So if you use slot 27 for an item, it will be set on the first slot at the next page.
