Checkbox for NOT filter
https://www.genesys-pgr.org/a/overview/v2aqrbXZdle lists 300+ Sphenostylis stenocarpa species, an African yam bean. The crop filter is suggested:
The user can either enable or disable this filter. There is no mechanism for the user to say "list all Sphenostylis stenocarpa where crop is not AYB".
A tri-state checkbox would allow the user to:
- Off: not applied
- Checked: crop === AYB
- Crossed-out: crop !== AYB
The "crossed-out" option specifies the NOT
filter.
