Collapsing Width instead of Height

[xaviergonz]

It would be really great if it supported a collapse-width mode

I initially thought it sounds like something trivial to do, but then realised there is still the case when we have width: auto and cannot easily do transition.

Will keep it opened for now as a feature idea, thanks.

Is there any alternative for this functionality on the market?

Not any I am aware of. Feel free to PR though.
