<strong>Usage:</strong> Toggle dropdown between showing/hidden.

### setChoices(choices, value, label);
|
||||
<strong>Input types affected:</strong> `select-one`, `select-multiple`
|
||||
|
||||
<strong>Usage:</strong> Set choices of select input via an array of objects, a value name and a label name. This behaves exactly the same as passing items via the `choices` option but can be called after initialising Choices.
|
||||
|
||||
<strong>Example:</strong>
|
||||
|
||||
```js
|
||||
const choices = new Choices(element);
|
||||
|
||||
choices.setChoices([
|
||||
{value: 'One', label: 'Label One', disabled: true},
|
||||
{value: 'Two', label: 'Label Two' selected: true},
|
||||
{value: 'Three', label: 'Label Three'},
|
||||
], 'value', 'label');
|
||||
```
|
||||
|
||||
### setValue(args);
|
||||
<strong>Input types affected:</strong> `text`
|
||||
|
||||
<strong>Usage:</strong> Set value of input based on an array of objects or strings. This behaves exactly the same as passing items via the `items` option but can be called after initialising Choices on an text input.

|

### setValueByChoice(value);
|
||||
<strong>Input types affected:</strong> `select-one`, `select-multiple`
|
||||
|
||||
<strong>Usage:</strong> Set value of input based on existing Choice.
|
||||
|
||||
<strong>Example:</strong>
|
||||
|
||||
```js
|
||||
const example = new Choices(element, {
|
||||
choices: [
|

{value: 'One', label: 'Label One'},
