React-Select-Checked
A React select component based on JedWatson/React-Select with checkmarks on selected options.
Installation
npm install react-select-checked --save
At this point you can import react-select-checked in your application as follows:
import CheckedSelect from 'react-select-checked';
Usage
React-Select-Checked generates a hidden text field containing the selected value, so you can submit it as part of a standard form. You can also listen for changes with the onChange
event property.
Options should be provided as an Array
of Object
s, each with a value
and label
property for rendering and searching. You can use a disabled
property to indicate whether the option is disabled or not.
The value
property of each option should be set to either a string or a number.
When the value is changed, onChange(selectedValueOrValues)
will fire, allowing you to re-render with an updated value=
prop.
var CheckedSelect = require('react-select-checked');
var options = [
{label: 'Chocolate', value: 'chocolate', disabled: true},
{label: 'Vanilla', value: 'vanilla'},
{label: 'Strawberry', value: 'strawberry'},
{label: 'Caramel', value: 'caramel'},
];
var currentSelection = [{label: 'Caramel', value: 'caramel'}];
function logChange(val) {
console.log('Selected value: ', val);
setState({currentSelection: val});
}
<CheckedSelect
name="form-field-name"
value={currentSelection}
options={options}
onChange={logChange}
/>
Async options
If you want to load options asynchronously, set async
attribute to true
and instead of providing an options
Array,
provide a loadOptions
Function.
The function takes two arguments String input, Function callback
and will be called when the input text is changed.
When your async process finishes getting the options, pass them to callback(err, data) in a Object { options: [] }
.
function logChange(val) {
console.log('Selected value: ', val);
setState({value: val});
}
function getOptions (input, callback) {
setTimeout(function() {
callback(null, {
options: [
{ value: 'one', label: 'One' },
{ value: 'two', label: 'Two' }
],
// CAREFUL! Only set this to true when there are no more options,
// or more specific queries will not be sent to the server.
complete: true
});
}, 1000);
}
<CheckedSelect
async
loadOptions={getOptions}
onChange={logChange}
placeholder="Select your favourite(s)"
value={value}
/>
Async options with Promises
loadOptions supports Promises, which can be used in very much the same way as callbacks.
function logChange(val) {
console.log('Selected value: ', val);
setState({value: val});
}
function getGitHubUsers(input) {
return fetch(
'https://api.github.com/search/repositories?q=stars:%3E1+language:javascript&sort=stars&order=desc&type=Repositories'
).then(
response => {
return response.json();
}).then(json => {
let githubUsers = json.items.map(user => {
return {
label: user.full_name,
value: user.name
};
});
return { options: githubUsers };
});
}
<CheckedSelect
async
loadOptions={getGitHubUsers}
onChange={logChange}
placeholder="Select your favourite(s)"
value={value}
/>
