Need help in wordpress with woocommerce

Currently I am working on a wedding website built in wordpress with woocommerce. It contains vendors, products and packages.

– first vendor with vendor category,
– then product where we can choose vendor for a product

– then comes the package where I need to show all the product categories as a tab
– then when I select a tab (for ex say wedding cakes), then I need to show all the vendors first as a drop down and when I select a particular vendor I am able to show the products of that particular vendor

– is there any way we can do this in wordpress, any available plugins for this??
– now I am customizing the wp and able to get till the above section (I am getting the two drop downs)
– but when I tried to save this it is not storing both the values in the database
– also I need to add more vendors and products for a single category tab

Any fast help on this will be much appreciated, struck on this for the past 1 week

Thanks
