React Bulma dropdown

It's a Bulma's dropdown, with an auto-height, scroll and portal support.

The .dropdown-menu is not simply rendered below the .dropdown-trigger, but is portaled to another DOM element. Thanks to that your dropdown will work in element that has overflow:hiden or overflow:scroll CSS style.

The .dropdown-menu is auto resizing to match the portal's bottom edge.

Installation

yarn add react-bulma-dropdown

You have also to include the dist/main.css file.

import Dropdown from 'react-bulma-dropdown'

<Dropdown trigger="Choose">
  <a href="#" className="dropdown-item">Item A</a>

</Dropdown>
