As an ES module

Cupertino Pane package comes with ES module version which can be used where supported or with bundlers like Webpack or Rollup:

import { CupertinoPane, CupertinoSettings } from 'cupertino-pane';

let settings: CupertinoSettings = { /* ... */ };
let myPane = new CupertinoPane('.cupertino-pane', settings);
    await myPane.present({animate: true});

Class creation

You can pass html element or string selector to class constructor

// String selector
new CupertinoPane('.cupertino-pane');

// HTML element
let element = document.querySelector('.cupertino-pane');
new CupertinoPane(element); // HTMLElement

draggableOver boolean true Render rectangular shape over a pane
clickBottomOpen boolean true If bottom position reached, simple click to pane will open pane to the next upper point
dragBy string[] null Array of selectors for whom elements drag events will be attached. By default drag events attached to pane element. If you are about to drag only with draggable component set option to ['.pane .draggable']
preventClicks boolean true Prevent accidental unwanted clicks events during move gestures
handleKeyboard boolean true Pane will be pushed up on open keyboard (only for cordova/capacitor/phonegap applications)
touchMoveStopPropagation boolean false If enabled, then propagation of "touchmove" will be stopped
simulateTouch boolean true Simulate touch events for Desktop
passiveListeners boolean true (Indicates that the function specified by listener will never call preventDefault())


Package now supports 3 base breakpoints

const pane = new CupertinoPane('.cupertino-pane', { 
  breaks: {
    top: { // Topper point that pane can reach
      enabled: true, // Enable or disable breakpoint
      height: 700, // Pane breakpoint height
      bounce: true // Bounce pane on transition
    middle: { ... },
    bottom: { ... }

Bottom and middle heights normalized accross devices by default

Default top height: window.screen.height - (135 * 0.35)

Add property bounce to break and enjoy transitions in apple stocks style with cubic-bezier(0.175, 0.885, 0.370, 1.120)


Configuration for 3D push effects and z-stack

let settings = {
  zStack: {
    pushElements: ['.card-1', '.main-content'],
    pushYOffset: 10
Property Type Default Description
pushElements string[] null DOM Element will be pushed and scaled
minPushHeight number null Height from which 3d push effect will be started
cardYOffset number null Margin value to place pushed elements upper
cardZScale number 0.93 Scale value for each pushed element
cardContrast number 0.85 Contrast value for each pushed element
stackZAngle number 160 Value from 0 to 3000 that define angle of z-stack in common. 0 - 150 positive expontial angle. 150 - 170 = 45 degree angle. 200 - 3000 negative exponential angle


The function that executes when the event fires. | Name | Type | Description | | ---- | ---- | ----------- | | onDidDismiss | void: () => {} | Call after pane will dissapeared | | onWillDismiss | void: () => {} | Call before pane will dissapeared | | onDidPresent | void: () => {} | Call after pane will present | | onWillPresent | void: () => {} | Call before panel will present | | onDragStart | void: () => {} | Call when detect user drag event on pane | | onDrag | void: () => {} | Call executes on each new position of pane | | onDragEnd | void: () => {} | Executes when drag event complete | | onBackdropTap | void: () => {} | Call when user tap backdrop overlay | | onTransitionStart | void: () => {} | Executes before auto transition and animation start | | onTransitionEnd | void: () => {} | Executes when transition and animation complete |

Public Methods

present({animate: boolean = false}): Promise

Will render pane DOM and show pane with setted params.


moveToBreak('top' | 'middle' | 'bottom')

Will change pane position with animation to selected breakpoint.


moveToHeight(val: number)

Will move pane to exact height with animation. Breakpoints will saved.



Dissappear pane from screen, still keep pane in DOM.


destroy({animate: boolean = false}): Promise

Remove pane from DOM and clear styles



Determinate if pane position was moved out of screen, but pane still exist in DOM. true - in DOM but not visible, false - in DOM and visible, null - not rendered

if (myPane.isHidden()) {


Method return current break position in text format ('top' | 'middle' | 'bottom)

if (myPane.currentBreak() === 'top') {


Method disable any drag actions for pane



Method enable any drag actions for pane


backdrop({show: boolean = true})

Show/Hide backdrop method

myPane.backdrop({show: true}); // show
myPane.backdrop({show: false}); // hide

setBreakpoints(breakpoints: PaneBreaks)

Method updates breakpoints configuration for rendered Pane

  top: {
      enabled: true,
      height: 700,
      bounce: true
  middle: { ... },
  bottom: { ... }

preventDismiss(boolean = false)

Use this method to prevent dismiss events. Use onWillDismiss() callback to listen if dismiss event prevented.

const settings = {
  onWillDismiss: (e) => {
    if (e) {

const myPane = new CupertinoPane('.cupertino-pane', settings);
myPane.present({animate: true});


Force re-calculate height for fitHeight: true in cases when height was calculated not properly.




Set for element to automaticaly hide on reach bottom breakpoint.

<div class="cupertino-pane">
    <div class="content" hide-on-bottom>Content</div>    


Set for element with overflow ability. By default using for full pane area, but in some cases good useful with header.

<div class="cupertino-pane">
    <div class="content" overflow-y>Content</div>    

CSS Variables

Variable Default
--cupertino-pane-background #ffffff
--cupertino-pane-color #333333
--cupertino-pane-shadow #0 4px 16px rgba(0,0,0,.12)
--cupertino-pane-border-radius #20px
--cupertino-pane-move-background #c0c0c0
--cupertino-pane-destroy-button-background #ebebeb
--cupertino-pane-icon-close-color #7a7a7e

Keyboard issues

Inputs and textareas in pane may push mobile keyboard on devices, and close pane visibility. Next cases describe how to proper handle this issues.


User's must use input focus/blur callback's to handle keyboard. Example:

<input onfocus="keyboardOpen()" onblur="keyboardClose()" />
function keyboardOpen () {
  pane.moveToBreak('top'); // or moveToHeight(current + keyboardHeight);
function keyboardClose () {
  pane.moveToBreak('middle'); // or moveToHeight(current - keyboardHeight);


By default, we are now handle keyboard in hybrid mobile applications and push pane to exact keyboard height. If you would like handle this part by yourself, set option handleKeyboard: false.
