This module is an etch component that can be used in Atom packages to show a select list with fuzzy filtering, keyboard/mouse navigation and other cool features.
npm install --save atom-select-listAfter installing the module, you can simply require it and use it as a standalone component:
const SelectList = require('atom-select-list')
const usersSelectList = new SelectList({
items: ['Alice', 'Bob', 'Carol']
})
document.body.appendChild(usersSelectList.element)Or within another etch component:
render () {
return (
<SelectList items={this.items} />
)
