Too slow when editing a product with variation

I found this plugin and it worked for me and I think it’s worth checking.

Good suggestion from @toknatz. Also have a look at this plugin which may help you set up your product with less variations:

@toknatz, @lorro Are those plugins are able to manage stock? Because some of our product variations are limited and must monitor stock movement. Thanks for the info in advance.

product-add-ons is really about all those optional extras which are free or included in the price and don’t affect stock levels, but which could otherwise exponentially increase the number of variations leading to the problems you describe.

Oh, yeah you can still use the “manage stock” for each variation/attribute and I think it’s pretty much the same the way we used to do a normal woocommerce variation.
I like the idea where you can mass update on the fly using the advance option.
I have csv importer as well and now I can change anytime without going to my csv file and import.

Thank you guys for your inputs and I really appreciate it.

I have updated the woocommerce too many variations plugin today and the new version have added other stuffs such as product add-on and a variation image.

Now I can setup different product variation images and the customer has the ability to preview that image in the front-end whenever they choose from the variation drop-down.

Before, I struggled a lot with variations but with this plugin managing is easy.
