Enable Disable a section or part of section depending on window.location.hostname within a template .json ?

[dshahin123]

Hi
Not sure if this is possible? Very new to all of this.
But here is what I am looking to do:
The "collapsible_row-4" is only required when accessing this page on our .fr & .it domains and so I would like to only make it enabled on those pages - I was trying to form some sort of if/else statement based on window.location.hostname == our .fr || .it domains but I cannot seem to get it to work? Any help would be greatly appreciated! (I have attached the whole .json file & also the .liquid for the collapsible content it is calling for this section)
