💥 Demo Page

React issue template: https://codesandbox.io/s/tagify-react-issue-template-forked-fs8fk4?file=/src/index.js

Explanation

• What is the expected behavior? Tag with value 0 is selectable

• What is happening instead? Tag with value 0 is not selectable (see the demo page for demonstration)

• What error message are you getting? No error message

Additional details: after a brief debug session the issue looks to be in the normalizeTags method during evaluating of isCollection variable: isCollection = isArray && tagsItems[0].value, In this case when value is not 0 the variable is evaluated as true, whereas if it's 0 it is evaluated as false. Possible solution: check for value 0 specifically.
