sysvisionz-react-dropdown

This module allows you to utilize a simple, highly customizable dropdown menu that can be used in pretty much any way you see fit; a link menu, a traditional selector, however. It allows you to dictate both the direction the menu initially "drops" from the original button, as well as the direction it "pops" outward from that original point, give each part styles or classes, put functions triggered by an item being selected, as well as the menu opening, closing, or every time it is toggled open or closed, control whether the menu is open through a value supplied from elsewhere, dictate if clicking outside the menu will close it or keep it open... or none of these things. It's a handy dandy toolbox of infinite possibilities and ridiculous simplicity!

Getting Started

To install, in terminal type

	npm i --save sysvisionz-react-dropdown

then, in your react project,

import Dropdown from 'sysvisionz-react-dropdown';

and finally, implement it by including that component within your code:

<Dropdown {options}>
    {children}
</Dropdown>

Using the Selector element

The Selector element was introduced in 5.0 as a simplified version of the dropdown that

Required Props

children

Content of the activating button.

content

Type: Array of [String || React Element]
behavior: dictates the children of the entries in the dropdown menu.

Optional Props

drop

accepted types: 'up', 'down', 'left', 'right'
default: 'down'
behavior: This dictates the direction that your dropdown menu drops out of the activating button. downLeft and upLeft are special variants; they render a normal drop, but orient the menu's edge to the opposite of the basic version (to the right edge for downLeft and upLeft, and to the bottom edge for rightUp and leftUp) to the activating button instead of the left edge. Note that, due to their nature, they make the pop prop unnecessary by definition.

pop

accepted types: 'up', 'down', 'left', 'right'
default: drop
note: cannot be opposite of drop.
behavior: This dictates the direction that your dropdown menu pops outwards from the inital dropped out element.

orientation

accepted types: 'top', 'bottom', 'left', 'right', 'center'
behavior: controls the dropdown menu relative to the activating button. 'center' will make a menu dropping downwards appear centered beneath the activating button, 'left' will make the right edge of the menu align with the right edge of the activating button, 'top' aligns the bottom edge with the bottom edge of the activating button, and so on.

open

type: Boolean
default: false
note: need not be set unless controlled is true. behavior: Whether the dropdown is open or not.

controlled

type: Boolean
behavior: dictates whether the menu is opened and closed by an outside variable (which is supplied through the open prop).

keepOpen

type: boolean
default: controlled
behavior: Dictates if dropdown menu will stay open when clicking outside it or on the entries in the menu. Menu can still be closed by clicking on the activating button note: if you do set this to false while controlled is true, it is highly recommended that you use the onToggle function to reset open!

onToggle

type: function
supplies: Boolean of current open state of menu.
behavior: function performed when menu is opened or closed.

onOpen

type: function
behavior: function performed when menu is opened.

onClose

accepted types: function
behavior: function performed when menu is closed.

slideIn

accepted types: Boolean
behavior: The menu does a smooth slide in animation.

fadeIn

accepted types: Boolean
behavior: The menu does a smooth fade in animation.

transition

accepted types: Number
behavior: Delays menu close for this many milliseconds, for the purposes of manually applied css transitions.

className

type: String
behavior: dictates the className for the overall element. Adds to prefix of svz-dropdown-container and is followed by active when the menu element is open.

id

type: String
behavior: dictates the id for the dropdown containing div

Prerequisites

As this is a React element, it doesn't run outside of a React environment.
