Installation

Make sure that you inserted the following link tag between the <head></head> tags inside /public/index.html of your react project. This is required for the FontAwesome component that the package depends on.

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" />

Usage

First, import the components:

import {DropdownMultiple, Dropdown} from 'reactjs-dropdown-component';

The structure of the state for the dropdown data should be as follows:

state = {
  location: [
    {
      id: 0,
      title: 'New York',
      selected: false,
      key: 'location'
    },
    {
      id: 1,
      title: 'Dublin',
      selected: false,
      key: 'location'
    },
    {
      id: 2,
      title: 'Istanbul',
      selected: false,
      key: 'location'
    }
  ],
  fruit: [
    {
      id: 0,
      title: 'Apple',
      selected: false,
      key: 'fruit'
    },
    {
      id: 1,
      title: 'Orange',
      selected: false,
      key: 'fruit'
    },
    {
      id: 2,
      title: 'Strawberry',
      selected: false,
      key: 'fruit'
    }
  ]
}

Then you need to include a function to control the state of the parent component.

This is for the single selection dropdown:

resetThenSet = (id, key) => {
  let temp = JSON.parse(JSON.stringify(this.state[key]));
  temp.forEach(item => item.selected = false);
  temp[id].selected = true;
  this.setState({
    [key]: temp
  });
}

And this is for the multi selection dropdown:

toggleItem = (id, key) => {
  let temp = JSON.parse(JSON.stringify(this.state[key]));
  temp[id].selected = !temp[id].selected;
  this.setState({
    [key]: temp
  });
}

Finally use the components as follows:

<Dropdown
  title="Select fruit"
  list={this.state.fruit}
  resetThenSet={this.resetThenSet}
/>

<DropdownMultiple
  titleHelper="Location"
  title="Select location"
  list={this.state.location}
  toggleItem={this.toggleItem}
/>

Note that when multiple options are selected in DropdownMultiple, titleHelper value gets an s letter appended. If you want to use a custom plural title, define titleHelperPlural as well.

<DropdownMultiple
  titleHelper="Sted"
  titleHelperPlural="Steder"
  title="Velg sted"
  list={this.state.location}
  toggleItem={this.toggleItem}
/>

Search functionality

Using searchable prop enables the search bar. Pass an array of strings corresponding to place holder and not found message respectively.

<Dropdown
  searchable={["Search for fruit", "No matching fruit"]}
  title="Select fruit"
  list={this.state.fruit}
  resetThenSet={this.resetThenSet}
/>
