Dynamically generate different types of orders, how do I deposit to mongo database?

Administrators use the form designer in the background to dynamically create dozens of different types of products (such as recharge orders, commodity orders, etc.), when the user submits the order, the conventional idea is to store the same fieldsInto the main table of the order, different fields are stored in the sub-table.
But these sub-tables cannot be prepared in advance because they are dynamically generated for different types of orders.
If these different types of order information are stored in the same field in the order table, will this affect the analysis and statistics of the data in the future?
So I want to ask the big guys, I hope you can give me some ideas or solutions, thank you~

My temporary solution is to store directly in the order table no matter what type of business order data..
