react-select is very nice, but sometimes project requirements are beyond it's abilities

$3

import:

import Select from "react-dropdown-select";

and use as:

``jsx
const options = [
{
value: 1,
label: 'Leanne Graham'
},
{
value: 2,
label: 'Ervin Howell'
}
];

this.setValues(values)} />;
`

If your options don't have value and label fields, include labelField and valueField in the props:

`jsx
const options = [
{
id: 1,
name: 'Leanne Graham'
},
{
id: 2,
name: 'Ervin Howell'
}
];

options={options}
labelField="name"
valueField="id"
onChange={(values) => this.setValues(values)}
/>;
`

> options and onChange are the minimum required props
