Hi Alexandre,
That’s an interesting use case. If I’m understanding correctly, you want the mobile version of Month View to display on desktop, but retain the tooltips from the desktop version in the mobile view–is that correct?
If so, I’d say that can get a little tricky and is pretty outside what we can help support here in the forums–but I’d be happy to point you in the right direct as best I can.
The tooltips are generated by JS. When the Month View switches from desktop to mobile, the month/tooltip.php template is affected by the month/mobile.php template. I would imagine that those are the two files you are going to want to work with so that the scripts in mobile.php do not replace the ones called by tooltip.php.
Sorry I don’t have a concrete solution for you here, but I do hope this at least gets you started!
