I’ve been building a dashboard for drilling down into data and I wanted to sync the options for all the multiselect components such that you don’t see opt…

Thanks Shawn, but that is only one-way dependency. My code syncs both ways so that if you change the second multiselect, the first one’s options update to only show what is available.

Hi, can you illustrate your bi-directional dependencies with actual data examples? Cheers

The code I posted illustrates the bi-directional syncing.

Hi - I thought this was interesting. It didn’t quite work for me. E.g., select a couple of regions and one car from the reduced set, then it falls over. Similarly, if you select two or more cars of different regions, then select one of the reduced set of regions, then it also falls over.
