I have hundreds of asset layers and want to get a count of the number of features in each one. Bonus would be to have that broken down by an attribute type within it.
It would be great if Ops Dashboard or Web App Builder supported this, but it looks like they only deal with individual layers.
You can use the info summary widget in WAB to display feature counts
You could also customize this to display all features with the Developer edition of WAB
Yeah, I have been using the Info Summary widget but it seems to only show the sum of one attribute at a time. If the dev edition will work, I'll try that route.
