Hi,
Thanks for the link.
I think you should set the type of layout ("Type de mise en page") in order to access to the options.
At this moment, you will be able to select the "type of item layout" and select a layout without the description.
For the moment, you use the default "product div" option from your HikaShop configuration "Display > Default parameters for DIVs > Type of item layout".
You can change the value here and stay as "inherit" for your content menu configuration.
