Hello,
Your answer was already in my previous message
It requires a view override and a little modification in the HikaMarket core.
If you want to be able to use the "order status" popup within the order listing, you need to add the required javascript in the listing.
Best is to be able to get the order id from the return of the order status modification ; otherwise you can kept the value in a local JS variable (but I'm not found of).
If you want to be able to update a specific order status, you must be able to find the HTML element and update it with the content.
But to find that HTML element, you need to have the knowledge of the order ID which has been just update.
Since my last message, I worked on an implementation but that's not something I can post here.
But that's something that we think about for the next release.
Regards,
