Hi Leebrosus,
I hope you are well!
Everything is working great. It is true that there is a slight latency with the pop-up ”Choose option” but otherwise everything is fine, again thank you for your help!
We would need some additional information:
1. How can we change the words ”Choose option” (”Choice of options” in our case) by ”Add to my box”?
2: We want to reorganize your widget ”Product category” (
).
We would like the products to be displayed in ”grid” on 2 columns without line limit, as on the current page ”Shop” (in mobile version). Indeed, the carousel is not necessarily very intuitive and many of our customers get lost because of it.
Here is an example of what we want: 
Thank you for your help and see you soon.
