npm install reactjs-dropdown-component --save
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" />
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:
toggleSelected = (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.toggleSelected}
/>Refer to the GitHub repository for the full code example.
