Hi,
It was suggested to post here to get an update from the Dashboard developer team on the status of the ArcGIS Dashboard Idea post "More query operators for the Category Selector in ArcGIS Online Operations Dashboard"
This idea was posted in 2018 and has shown 'Under Consideration'. I really like the functionality of dashboards but the selectors are limited to equals/does not equal. As folks have stated in support of the idea, it is essential functionality. How else can you filter fields with list of values?
Thanks for the update,
Kathy
This idea has now been implemented, the 'contains' operator can now be used in Dashboards to filter on strings.
