(Solved)I need help with mods production

[tpmove]

I am a novice mod maker and have learned how to create a handheld item. But now I want to make a building, and I don't know what its necessary components are. Its basic function is to have four compartments, place an item, and then click the button to convert it to another item in the backpack item column.

The problem has been resolved

[tpmove]

After studying, I have now realized how to place it on the ground, but how to make it open like a box and put items inside?

[tpmove]

Now I have implemented it as a box, which generates a set of ice when I close it, but when I open the dedicated server, it will report an error

This is the error log

[00:01:41]: [string "scripts/widgets/containerwidget.lua"]:31: attempt to index local 'widget' (a nil value)

Wow, that's great. It worked. Thank you！
