Input Tags JS: a lightweight vanilla JavaScript library for adding tag input fields with autocomplete to HTML forms.
Key features:
- Zero dependencies. Pure vanilla JS
- Predefined tag list with alias search
- Group-based exclusivity (one tag per group allowed)
- Custom user-defined tags with blacklist support
- Full keyboard navigation
- Clean programmatic API for runtime control
It submits data via hidden form fields, so it works with any server stack.
