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.
Refer to the following styling file for overriding the default styles. You can create your own styling file with the same class names in order to do your custom styling.
