Vizualizations allow only single value filtering via Cross filters

[milenioz]

Expected results

When a viz is set to emit filters for Cross filtering further selection from it in a dashboard allow only single value selection while in v 1.2.0 it was possible to emit multi value filters

Screenshots

Current master branch V1.2.0:

How to reproduce the bug

1. Go to 'USA Births Names'
2. Edit table "Boys" in Explore chart. Enable "Emit filtering".
3. Reload "USA Births Names"
4. Click on any name in "Boys" table. (e.g Michael)
5. Dashboard is filtered by the selected name
6. Click on another name in 'boys" table. Dashboard is filtered by the second selected name (e.g. David)

In V1.2.0 from pip installation selecting the second name allows the Dashboard to be filterd by the multiple selected names, adding them as "name IN ('Michael', 'David')" in the where clause of other viz in the dashboard.

@milenioz only allow single select was the the scope for last stage of the project. we are working on multiple select currently. would you like to participate?

[milenioz]

[junlincc]

@milenioz no worries:) we will let you know once the feature is ready for testing. one thing that you could help i sharing your best x-filerting experience with any other bi tools so far. 🙏 how would you expect multiple select work on dashboard?

Moving this to a discussion, since clearly there's interest, but it's not a bug. Yes, this "worked" for a minute when we were first building cross-filters, but there were MANY complications and edge cases in actually getting it to work in all chart types (both emitting and receiving these filters). This is not on any PMC member roadmaps that I'm aware of, but if anyone wants to contribute it (probably after a SIP, and behind a new feature flag until it's stable), then by all means, go for it!
