Custom Entity Json Array

[Falerci]

Hi all,

I would like to create a specific Json Array custom field.

Pretty sure that it needs development, I'm also assuming that I might start from the Opportunity Item code.

Can you help me to create the custom field and the visualization layout?

Thanks

Attached you can find an example of what I'm looking for.

I doubt anyone can help you Falerci, I want something like this too but unfortunately there two issue that make it not possible as far as I'm can see on the forum.

(1) It can't use the Sale Packs code (official paid extension)
(2) Too much work, require paying a developer to put hours in coding it.
