        items={items}
        uniqueKey="id"
        onSelectedItemsChange={this.onSelectedItemsChange}
        selectedItems={this.state.selectedItems}
        selectText="Pick Items"
        searchInputPlaceholderText="Search Items..."

        tagBorderColor="#CCC"
        tagTextColor="#CCC"
        selectedItemTextColor="#CCC"
        selectedItemIconColor="#CCC"
        itemTextColor="#000"
        searchInputStyle={{ color: '#CCC' }}
        submitButtonColor="#CCC"
        submitButtonText="Submit"
      />
    </View>
  }

The component takes 3 compulsory props - items, uniqueKey and selectedItemsChange. Other props are optional. The table below explains more.

Props

Prop	Required	Purpose
items	Yes	(Array, control prop) List of items to display in the multi-select component. JavaScript Array of objects. Each object must contain a name and unique identifier (Check sample above)
selectedItems	No	(Array, control prop) List of selected items keys . JavaScript Array of strings, that can be instantiated with the component
uniqueKey	Yes	(String) Unique identifier that is part of each item's properties. Used internally as means of identifying each item (Check sample below)
textColor	No	(String) Color for selected item name displayed as label for multiselect
fontSize	No	(Number) Font size for selected item name displayed as label for multiselect
fixedHeight	No	(Boolean) Defaults to false. Specifies if select dropdown take height of content or a fixed height with a scrollBar (There is an issue with this behavior when component is nested in a ScrollView in which scroll event will only be dispatched to parent ScrollView and select component won't be scrollable). See this issue for more info.
single	No	(Boolean) Toggles select component between single option and multi option
onSelectedItemsChange	Yes	(Function) JavaScript function passed in as an argument. The function is to be defined with an argument (selectedItems). Triggered when Submit button is clicked (for multi select) or item is clicked (for single select). (Check sample above)
selectText	No	(String) Text displayed in main component
searchInputPlaceholderText	No	(String) Placeholder text displayed in multi-select filter input
fontFamily	No	(String) Custom font family to be used in component (affects all text except searchInputPlaceholderText described above)
altFontFamily	No	(String) Font family for searchInputPlaceholderText
tagRemoveIconColor	No	(String) Color to be used for the remove icon in selected items list
tagBorderColor	No	(String) Border color for each selected item
tagTextColor	No	(String) Text color for selected items list
selectedItemFontFamily	No	(String) Font family for each selected item in multi-select drop-down
selectedItemTextColor	No	(String) Text color for each selected item in multi-select drop-down
selectedItemIconColor	No	(String) Color for selected check icon for each selected item in multi-select drop-down

itemTextColor	No	(String) Text color for each non-selected item in multi-select drop-down
searchInputStyle	No	(Object) Style object for multi-select input element
hideSubmitButton	No	(Boolean) Defaults to false. Hide submit button from dropdown, and rather use arrow-button in search field"
submitButtonColor	No	(String) Background color for submit button
submitButtonText	No	(String) Text displayed on submit button

Note

• When using the single prop, selectedItems should still be passed in as an array of selected items keys. Also, when an item is selected in the single mode, the selected item is returned as an array of string.

• The items props must be passed as an array of objects with a compulsory name key present in each object as the name key is used to display the items in the options component.

Removing all selected items

To use, add ref to MultiSelect component in parent component, then call method against reference. i.e.

<MultiSelect
  ref={c => this._multiSelect = c}
  ...
/>

clearSelectedCategories = () => {
   this._multiSelect.removeAllItems();
};
