I found the ngTagsInput framework
https://mbenford.github.io/ngTagsInput/
a very feature-rich library. But for Angular 8 users I found the ngx-chips framework
https://www.npmjs.com/package/ngx-chips
It appears to work, but appears to be missing some obvious features, or it the features are achievable they appear to be difficult to implement. For example: providing chips of different colors.
Questions:
1) Is ngx-chips the most capable replacement for ngTagsInput for the Angular 2+? is there something better?
2) I understand it's not recommended to use a angularjs library inside of Angular 2+? So using the ngTagsInput library can be used?
ngx-chips was the best opensource framework I found at this time. Documentation is a bit terse, but the software is self appears solid.
