# bootstrap-5-autocomplete

This is a rewrite of https://github.com/Honatas/bootstrap-4-autocomplete for bootstrap v5.

### Example

```js
const ac = new Autocomplete(field, {
    data: [{label: "I'm a label", value: 42}],
    maximumItems: 5,
    onSelectItem: ({label, value}) => {
        console.log("user selected:", label, value);
    }
});

// later, when you need to change the dataset

ac.setData([
    {label: 'New York JFK', value: 'JFK'},
    {label: 'Moscow SVO', value: 'SVO'},
]);
```

### Options

**data**:  
The data from where autocomplete will lookup items to show. This data has to be an array of JSON objects. The format for every item in the array is:

    {"label": "This is a text", "value": 42}

**dropdownClass**:

**maximumItems**:
