Hello Elise,
ok let me rephrase it please
i deleted the 3 import layouts tests from here : https://gyazo.com/6147fe816e85bbb5489b037095ceffa3

they are not of any use for me

so now there is nothing in the list

so now i am back to the original design of product page that i like and that i want to play with, please see :

https://vb8srz3fkb7.c.updraftclone.com/blog/produit/boite-de-vitesses-renault-maxity-2-5-dci-6-vitesses-2/

here it is, this one has a structure of course, and this has not been created by any layout import feature, it was part of the demo i initially imported 3 yars ago

so to summ up, i have a design of single product page that i like, the url i sent you, and i cannot modify its structure because it does not appear in any layout

but now i want to play with its structure, on wpbakery

how can i do so ?
