Hi looking for a solution to create multiple options for one product with the different price. Example one product has Base Colour | Size | Storage. Inside Base Colour 23 options with different prices. Inside Size 10 options different prices. Inside Storage 5 options different prices.
How can I do this in Magento? Can someone guide me or give me hint how to do it? Because I can't figure out.
You can simply create Grouped Product for your problem
Grouped product have multiple simple/virtual product with set different price for each child product. You need to create first simple product with different options and different price and assigned that product to Grouped.
Check link for creating grouped product,
You can simply do it using grouped product concept.
