ReactJS - Dropdown Component

ReactJS Dropdown Component is a feature rich select / dropdown / typeahead component. It provides a default template that fits most use cases for a filterable select dropdown.

• configurable via props
• total custom components overrides for all internals via render prop callbacks (with access to internal props, state and methods)
• stylable via css (or custom components)
• portal support for rendering dropdown outside local DOM tree. e.g. in document.body
• auto position
• small bundle size
