Styling

Look at react-tagsinput.css for a basic style.

Component Interface

$3

##### value (required)

An array of tags.

##### onChange (required)

Callback when tags change, gets three arguments tags which is the new
tag array, changed which is an array of the tags that have changed and
changedIndexes which is an array of the indexes that have changed.

##### onChangeInput

Callback from the input box, gets one argument value which is the content of the input box.
(onChangeInput is only called if the input box is controlled, for this to happen both inputValue and onChangeInput need to be set)

##### addKeys

An array of keys or key codes that add a tag, default is [9, 13] (Tab and Enter).

##### currentValue

A string to set a value on the input.

##### inputValue

Similar to currentValue but needed for controlling the input box. (inputValue is only useful if you use it together with onChangeInput)

##### onlyUnique

Allow only unique tags, default is false.

##### validate

Allow only tags that pass this validation function. Gets one argument tag which is the tag to validate. Default is () => true.

##### validationRegex

Allow only tags that pass this regex to be added. Default is /.*/.

##### onValidationReject

Callback when tags are rejected through validationRegex, passing array of tags as the argument.

##### disabled

Passes the disabled prop to renderInput and renderTag, by default this
will "disable" the component.

##### maxTags

Allow limit number of tags, default is -1 for infinite.

##### addOnBlur

Add a tag if input blurs. Default false.

##### addOnPaste

Add a tags if HTML5 paste on input. Default false.

##### pasteSplit

Function that splits pasted text. Default is:

`javascript
function defaultPasteSplit (data) {
return data.split(' ').map(d => d.trim())
}
`

##### removeKeys

An array of key codes that remove a tag, default is [8] (Backspace).


##### className

Specify the wrapper className. Default is react-tagsinput.


##### focusedClassName

Specify the class to add to the wrapper when the component is focused. Default is react-tagsinput--focused.


##### tagProps

Props passed down to every tag component. Default is:
`javascript

classNameRemove: 'react-tagsinput-remove'
}
`

##### inputProps

Props passed down to input. Default is:

`javascript
{
className: 'react-tagsinput-input',
placeholder: 'Add a tag'
}
`

##### tagDisplayProp

The tags' property to be used when displaying/adding one. Default is: null which causes the tags to be an array of strings.

##### renderTag

Render function for every tag. Default is:

`javascript
function defaultRenderTag (props) {
let {tag, key, disabled, onRemove, classNameRemove, getTagDisplayValue, ...other} = props
return (

{getTagDisplayValue(tag)}
{!disabled &&
onRemove(key)} />
}

)
}
`

##### renderInput

Render function for input. Default is:

`javascript
function defaultRenderInput (props) {
let {onChange, value, addTag, ...other} = props
return (

)
}
`

Note: renderInput also receives addTag as a prop.

##### renderLayout

Renders the layout of the component. Takes tagElements and inputElement as args. Default is:

`javascript
function defaultRenderLayout (tagElements, inputElement) {
return (

{tagElements}
{inputElement}

)
