Update two widgets at same time

Is it possible to update two widgets simultaneously without a for loop; similar to widget.param.set_param(), but maybe like pn.set_param({widget1: {"value": 25}, "widget2": {"value": 35}})

I don’t think so, but @philippjfr would know for sure. Is your main goal to reduce verbosity and complexity, or to make it faster, or to set them into a mutually compatible set of values without intermediate errors caused by triggering watchers?

I’m similarly interested in such functionality. My use case is to synchronize multiple Card widgets so that once one of them gets minimized, all others follow suit. Using a for loop, It’s very noticeable they are not closed at the same time.

Similar as leogolds;
