-## Wut? Poppers?
-A popper is an element on the screen which "pops out" from the natural flow of your application.
-Common examples of poppers are tooltips and popovers.
-
-## So, yet another tooltip library?
-Well, basically, **no**.
-Popper.js is built from the ground up to being modular and fully ~~hackable~~ **customizable**.
-It supports a **plugin system** you can use to add particular behaviors to your poppers.
-It's **AMD** and **CommonJS** compatible and it's well documented thanks to our [JSDoc page](https://fezvrasta.github.io/popper.js/documentation.html).
-
-
-## The Library
-Popper.js is mostly a library with the job of making sure your popper stays near the defined reference element (if you want so).
-Additionally, it provides an easy way to generate your popper element if you don't want to use one already in your DOM.
-
-### Installation
-Popper.js is available on NPM and Bower:
-
-| Source | |
-|:---------|:---------------------------------------------|
-| NPM | `npm install popper.js@0 --save` |
-| Bower | `bower install popper.js#~0 --save` |
-| jsDelivr | `http://www.jsdelivr.com/projects/popper.js` |
-
-> **Heads up!** We are working on the v1.0.0 release of Popper.js, make sure to install the latest v0.* if you want to stay on the stable version!
-
-### Basic usage
-Create a popper near a button:
-
-```js
-var reference = document.querySelector('.my-button');
-var thePopper = new Popper(
- reference,
- {
- content: 'My awesome popper!'
- },
- {
- // popper options here
- }
-);
-```
-
-### "Advanced" usage
-Given an existing popper, ask Popper.js to position it near its button
-
-```js
-var reference = document.querySelector('.my-button');
-var popper = document.querySelector('.my-popper');
-var anotherPopper = new Popper(
- reference,
- popper,
- {
- // popper options here
- }
-);
-```
-
-### Callbacks
-```js
-var reference = document.querySelector('.my-button');
-var popper = document.querySelector('.my-popper');
-var anotherPopper = new Popper(reference, popper).onCreate(instance) {
- // instance is Popper.js instance
-}).onUpdate(function(data) {
- // data is an object containing all the informations computed by Popper.js and used to style the popper and its arrow
-});
-```
-
-### React.js and Ember.js integration
-If you prefer to let your framework apply the styles to your DOM objects, you can follow an approach like the one below:
-```js
-var reference = document.querySelector('.my-button');
-var popper = document.querySelector('.my-popper');
-var anotherPopper = new Popper(reference, popper, {
- modifiersIgnored: ['applyStyle'] // prevent Popper.js from applying styles to your DOM
-}).onUpdate(function(data) {
- // export data in your framework and use its content to apply the style to your popper
-});
-```
-You can find a fully working React.js component visiting this gist:
-https://gist.github.com/FezVrasta/6533adf4358a6927b48f7478706a5f23
-
-
-If you are wondering about the available options of the third argument, check out [our documentation](http://fezvrasta.github.io/popper.js/documentation.html#new_Popper_new)
-
-Visit our [GitHub Page](https://fezvrasta.github.io/popper.js) to see a lot of examples of what you can do right now!
-
-### Writing your own modifiers
-Popper.js is based on a "plugin-like" architecture, most of the features of it are fully encapsulated "modifiers".
-A modifier is a function that is called each time Popper.js needs to compute the position of the popper. For this reason, modifiers should be very performant to avoid bottlenecks.
-
-```
-// this little modifier forces the popper `top` value to be `0`
-function fixToTop(data) {
- data.popper.offsets.top = 0
- return data;
-}
-```
-
-Then, you can add your modifier to your Popper.js instance, adding it to the `modifiers` list in the options:
-
-```
-// note that the built-in modifiers are referenced using strings
-// instead, your custom modifiers are passed directly as functions
-new Popper(a, b, {
- modifiers: [ 'shift', 'offset', 'preventOverflow', 'keepTogether', 'arrow', 'flip', 'applyStyle', fixToTop]
-})
-```
-
-Here is the `data` object content:
-
-```
-let data = {
- // popper and reference elements positions
- offsets: {
- popper: {
- top: Number,
- left: Number,
- width: Number,
- height: Number
- },
- reference: {
- top: Number,
- left: Number,
- width: Number,
- height: Number
- },
- // here, only one of the two values will be different from `0`, depending by the placement
- arrow: {
- left: Number,
- top: Number
- }
- },
- // the result of the _getBoundaries method, these are the limits between the popper can be placed
- boundaries: {
- top: Number,
- right: Number,
- bottom: Number,
- left: Number
- },
- // `top`, `left`, `bottom`, `right` + optional `end` or `start` variations
- placement: String,
- // the placement defined at the beginning, before any edit made by modifiers
- _originalPlacement: String,
- // allows you to know if the `flip` modifier have flipped the placement of the popper
- flipped: Boolean,
- // the node of the arrow (if any)
- arrowElement: HTMLElement,
- // any property defined in this object will be applied to the popper element
- // here you can even override the default styles applied by Popper.js
- styles: {}
-}
-```
-
-
-## Libraries using Popper.js
-
-Popper.js will never winthe prize for "easiest to use tooltip library", well, probably because it's not a tooltip lib. 😅
-With it you can create awesome libraries without worring about the positioning problems! Some great ones using Popper.js are listed here:
-
-- [intro-guide-js](https://github.com/johanlahti/intro-guide-js): Create guided tours of your web pages;
-- [picker.js](https://github.com/GeekAb/picker.js): Modern date picker;

- /**
- * Create a new Popper.js instance
- * @constructor Popper
- * @param {HTMLElement} reference - The reference element used to position the popper
- * @param {HTMLElement|Object} popper
- * The HTML element used as popper, or a configuration used to generate the popper.
- * @param {String} [popper.tagName='div'] The tag name of the generated popper.
- * @param {Array} [popper.classNames=['popper']] Array of classes to apply to the generated popper.
- * @param {Array} [popper.attributes] Array of attributes to apply, specify `attr:value` to assign a value to it.
- * @param {HTMLElement|String} [popper.parent=window.document.body] The parent element, given as HTMLElement or as query string.
- * @param {String} [popper.content=''] The content of the popper, it can be text, html, or node; if it is not text, set `contentType` to `html` or `node`.
- * @param {String} [popper.contentType='text'] If `html`, the `content` will be parsed as HTML. If `node`, it will be appended as-is.
- * @param {String} [popper.arrowTagName='div'] Same as `popper.tagName` but for the arrow element.
- * @param {Array} [popper.arrowClassNames='popper__arrow'] Same as `popper.classNames` but for the arrow element.
- * @param {String} [popper.arrowAttributes=['x-arrow']] Same as `popper.attributes` but for the arrow element.
- * @param {Object} options
- * @param {String} [options.placement=bottom]
- * Placement of the popper accepted values: `top(-start, -end), right(-start, -end), bottom(-start, -right),
- * left(-start, -end)`
- *
- * @param {HTMLElement|String} [options.arrowElement='[x-arrow]']
- * The DOM Node used as arrow for the popper, or a CSS selector used to get the DOM node. It must be child of
- * its parent Popper. Popper.js will apply to the given element the style required to align the arrow with its
- * reference element.
- * By default, it will look for a child node of the popper with the `x-arrow` attribute.
- *
- * @param {Boolean} [options.gpuAcceleration=true]
- * When this property is set to true, the popper position will be applied using CSS3 translate3d, allowing the
- * browser to use the GPU to accelerate the rendering.
- * If set to false, the popper will be placed using `top` and `left` properties, not using the GPU.
- *
- * @param {Number} [options.offset=0]
- * Amount of pixels the popper will be shifted (can be negative).
- *
- * @param {String|Element} [options.boundariesElement='viewport']
- * The element which will define the boundaries of the popper position, the popper will never be placed outside
- * of the defined boundaries (except if `keepTogether` is enabled)
- *
- * @param {Number} [options.boundariesPadding=5]
- * Additional padding for the boundaries
- *
- * @param {Array} [options.preventOverflowOrder=['left', 'right', 'top', 'bottom']]
- * Order used when Popper.js tries to avoid overflows from the boundaries, they will be checked in order,
- * this means that the last ones will never overflow
- *
- * @param {String|Array} [options.flipBehavior='flip']
- * The behavior used by the `flip` modifier to change the placement of the popper when the latter is trying to
- * overlap its reference element. Defining `flip` as value, the placement will be flipped on
- * its axis (`right - left`, `top - bottom`).
- * You can even pass an array of placements (eg: `['right', 'left', 'top']` ) to manually specify
- * how alter the placement when a flip is needed. (eg. in the above example, it would first flip from right to left,
- * then, if even in its new placement, the popper is overlapping its reference element, it will be moved to top)
- *
- * @param {Array} [options.modifiers=[ 'shift', 'offset', 'preventOverflow', 'keepTogether', 'arrow', 'flip', 'applyStyle']]
- * List of functions used to modify the data before they are applied to the popper, add your custom functions
- * to this array to edit the offsets and placement.
- * The function should reflect the @params and @returns of preventOverflow
- *
- * @param {Array} [options.modifiersIgnored=[]]
- * Put here any built-in modifier name you want to exclude from the modifiers list
- * The function should reflect the @params and @returns of preventOverflow
- *
- * @param {Boolean} [options.removeOnDestroy=false]
- * Set to true if you want to automatically remove the popper when you call the `destroy` method.
