react-filtered-multiselect
A <FilteredMultiSelect/>
React component, for making and adding to selections using a filtered multi-select.
Live example with Bootstrap styles applied
Features
This component manages an <input>
, a <select multiple>
and a <button>
.
You provide a list of objects to be used to populate the select and an onChange
callback function.
Typing in the the input will filter the select to items with matching option text.
When some of the select's options are selected, the button will become enabled. Clicking it will select the objects backing the currently selected options.
If only one option is displayed after filtering against the input, pressing Enter in the input will select the object backing it.
When backing objects are selected, the onChange
callback is executed, passing a list of all backing objects selected so far.
To hide already-selected items, pass them back to FilteredMultiSelect
as its selectedOptions
prop. This can be more convenient than manually removing the selected items from the list passed as options
.
To deselect items, remove them from the list passed back via the onChange
callback and re-render the FilteredMultiSelect
with the new list passed as its selectedOptions
prop.
Double-clicking will add the selected option to the selection.

API
Required props
Minimal usage:
let options = [
{value: 1, text: 'Item One'},
{value: 2, text: 'Item Two'}
]
<FilteredMultiSelect
onChange={this.handleChange}
options={options}
/>
options
- list of objects providing <option>
data for the multi-select. By default, these should have text
and value
properties, but this is configurable via props.
The component will update its display if its options
list changes length or is replaced with a different list, but it will not be able to detect changes which don't affect length or object equality, such as replacement of one option with another. Consider using immutability-helper or other immutability libraries if you need to do this.
onChange(selectedOptions)
- callback which will be called with selected option objects each time the selection is added to.
Optional props
buttonText
- text to be displayed in the <button>
for adding selected <option>
s.
className
- class name for the component's <div>
container.
classNames
- class names for each of the component's child elements. See the default props below for properties. Defaults will be used for any properties not specified via this prop.
defaultFilter
- default filter text to be applied to the <select>
disabled
- disables each child element if true
.
placeholder
- placeholder text to be displayed in the filter <input>
.
selectedOptions
- list of option objects which are selected, so should no
longer be displayed in the <select>
.
showFilter
- pass false
to disable showing the filter input if you just use this component for selection.
size
- size
attribute for the <select>
textProp
- name of the property in each object in options
which provides
the displayed text for its <option>
.
valueProp
- name of the property in each object in options
which provides
the value
for its <option>
.
