Customization

Renderers

You can replace the renderers of the following components:

Item

Use the itemRenderer to replace the default component.

Each item receives the following props:

item - holds your item data

height - receives the height defined by the list

onClick - the event to toggle selection on the component

checked - indicates if the item is selected

indeterminate - used by the select all component to display indeterminate mode

disabled - defines if item should be disabled. Item won't be clickable for selection and will be ignored when clicking "Select All".

group - group item - no checkbox, not clickable, black colored

Select All

Use the selectAllRenderer to replace the default component.

The SelectAll component receives the following props:

height - receives the height defined by the parent

onClick - Triggers the select all/clear all event on click

isAllSelected - Indicates that all items are selected

selectAllMessage - Defines the message for the SelectAll component

selectedIds - holds a list of ids of all the selected items

Selected Item

Use the selectAllRenderer to replace the default component.

The SelectedItem component receives the following props:

item - holds your item data

height - receives the height defined by the list

You can disable specific selected items by passing item.disabled: true or pass isLocked function which will be used to define whether the item is disabled.

Example (selected & disabled):

function Exemple(){
  const items = [{id:0,label: 'item 0'}, {id:1,label: 'item 1'}];
  return (
        <MultiSelect
          isLocked={item => item.label === 'item 0'}
          items={items}
          selectedItems={items}
        />
}

Search

Use the searchRenderer to replace the default component.

The Search component receives the following props:

searchPlaceholder - defines the message to display in the search placeholder

onChange - triggers the action of changing the search value

Selection Status

Use the selectionStatusRenderer to replace the default component.

The SelectionStatus component receives the following props:

selected - an array of all the selected ids

clearAll - callback to clear all selected items

clearAllMessage - text to display in the clear all text

noneSelectedMessage - text to display when no items are selected

selectedMessage - text to display when there are items selected

Loader

Use the loaderRenderer to replace the default component.

Does not receive any props.

No Items

Use the noItemsRenderer to replace the default component.

Does not receive any props.

Search Function

In order to accommodate complex item filters, you can provide your own filter method in the filterFunction prop.

Example (default):

value => item =>
  String(item.label)
    .toLowerCase()
    .includes(value.toLowerCase())

Performs search on server side

value => {
    callServer(value).then(items => this.setState({items}));
    // At the end return the expected method
    return item => true;
}

Messages

You can use your own messages. Here is the default messages object:

 messages: {
    searchPlaceholder: "Search...",
    noItemsMessage: "No Items...",
    noneSelectedMessage: "None Selected",
    selectedMessage: "selected",
    selectAllMessage: "Select All",
    clearAllMessage: "Clear All",
    disabledItemsTooltip: "You can only select 1 file"
  }

Item grouping

You can add also grouping to your items - add a group prop with the group name as a value to each of your items and add withGrouping prop as well.

 <MultiSelect
    items={[{id: 1, label: "item1", group: "group1"},
            {id: 2, label: "item2", group: "group1"}
            {id: 3, label: "item3", group: "group2"}]}
    withGrouping
    selectedItems={selectedItems}
    onChange={this.handleChange}
  />
