Project description
We need a web programmer. An extension for the package of goods is required.
Make it possible to combine goods into sets (groups).
I mean. Goods A may consist of goods A (the goods themselves), A+B, A+B or A+G.
In the product card A, the user should be given the opportunity to select a set.
In a standard assembly, this can be implemented through the options of the product, but with a massive change in prices, you need to change prices with your hands a lot in the options.
We need to be able to assign goods instead of options.
Offer your price as there is no way to estimate the cost of such work
