One of the most time consuming tasks is selecting them in the vendor dashboard. I would like this to be a check box selection, just like it is in Woocommerce in the back end. You just scroll down, check the boxes where the product goes and it’s all done. With your system you have to scroll that same list up to 12 times per product!
I can understand your requirement for the category for the vendor @rayela. But every plugin/software has some technical limitations. As after hearing from you, I have checked few of plugins that offer this type of feature and found that they have the same procedure of selecting the category like us. Therefore, I am not aware how much it is technically possible to implement the backend look on the front end as the flow you required in offered by the WooCommerce’s backend.
However, I have noted down your requirement. If it is possible then definitely we would implement it as we want our plugin to be very user-friendly 🙂
