Hi,
Yes, you can use it. For example:
<smart-multi-combo-input id="employees"></smart-multi-combo-input>
<script>
    const multiCombo = document.getElementById('employees');
    // Fetch data from REST API
    fetch('https://api.example.com/employees')
        .then(response => response.json())
        .then(data => {
            // Assuming API returns: [{id:1, name:"Alice"}, {id:2, name:"Bob"}]
            multiCombo.dataSource = data.map(emp => emp.name);
        })
        .catch(error => console.error('Error fetching employees:', error));
</script>
