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


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


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

The SelectionStatus component receives the following 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: "delected",
    selectAllMessage: "Select All",
    clearAllMessage: "Clear All",
    disabledItemsTooltip: "You can only select 1 file"
  }
