Viewport Manager

Viewport manager contains a collection of available screen types that can be used on the theme. It is also responsible for triggering event viewport:change through the mediator, when the type of the screen changes. It is possible to subscribe to event viewport:change in view and create a logic based on the viewport changes (for example, DOM Relocation View).

Screen Map

By default these settings for list of screen types synchronized with scss breakpoints.

// Desktop Media Breakpoint
$breakpoint-desktop: 1100px;

// iPad mini 4 (768*1024), iPad Air 2 (768*1024), iPad Pro (1024*1366)
$breakpoint-tablet: $breakpoint-desktop - 1px;
$breakpoint-tablet-small: 992px;

// iPhone 4s (320*480), iPhone 5s (320*568), iPhone 6s (375*667), iPhone 6s Plus (414*763)
$breakpoint-mobile-big: 767px;
$breakpoint-mobile-landscape: 640px;
$breakpoint-mobile: 414px;
$breakpoint-mobile-small: 360px;

$oro_breakpoints: (
    'desktop': '(min-width: ' + $breakpoint-desktop + ')',
    'tablet': '(max-width: ' +  $breakpoint-tablet + ')',
    'strict-tablet': '(max-width: ' +  $breakpoint-tablet + ') and (min-width: ' + ($breakpoint-tablet-small + 1) + ')',
    'tablet-small': '(max-width: ' +  $breakpoint-tablet-small + ')',
    'strict-tablet-small': '(max-width: ' +  $breakpoint-tablet-small + ') and (min-width: ' + ($breakpoint-mobile-landscape + 1) + ')',
    'mobile-landscape': 'screen and (max-width: ' +  $breakpoint-mobile-landscape + ')',
    'strict-mobile-landscape': '(max-width: ' +  $breakpoint-mobile-landscape + ') and (min-width: ' + ($breakpoint-mobile + 1) + ')',
    'mobile': '(max-width: ' + $breakpoint-mobile + ')',
    'mobile-big': '(max-width: ' +  $breakpoint-mobile-big + ')',
);

Default scss breakpoints are converted to the following array:

screenMap: [
    {
        name: 'desktop',
        min: 1100
    },
    {
        name: 'tablet',
        max: 1099
    },
    {
        name: 'strict-tablet',
        max: 1099,
        min: 993
    },
    {
        name: 'tablet-small',
        max: 992
    },
    {
        name: 'strict-tablet-small',
        max: 992,
        min: 641
    },
    {
        name: 'mobile-big',
        max: 767
    },
    {
        name: 'strict-mobile-big',
        max: 767,
        min: 641,
    },
    {
        name: 'mobile-landscape',
        max: 640
    },
    {
        name: 'strict-mobile-landscape',
        max: 640,
        min: 415
    },
    {
        name: 'mobile',
        max: 414
    },
    {
        name: 'mobile-small',
        max: 360
    }
]

You can override these breakpoints via scss variables.

Overriding via js Module Config for a Theme

This config has the highest priority:

{% import '@OroAsset/Asset.html.twig' as Asset %}
{{ Asset.js_modules_config({
        'oroui/js/viewport-manager': {
            screenMap: [
                {
                    name: 'tablet',
                    max: 640
                },
                {
                    name: 'desktop',
                    max: 1260
                },
                {
                    name: 'desktop-hd',
                    max: 1920
                }
            ]
        }
}); }}

To delete an inherited screen type, set skip: true for a specific screen name:

{% import '@OroAsset/Asset.html.twig' as Asset %}
{{ Asset.js_modules_config({
        'oroui/js/viewport-manager': {
            screenMap: [
                {
                    name: 'tablet',
                    skip: true
                },
                {
                    name: 'desktop',
                    max: 1260
                }
            ]
        }
    }
}); }}

Screen Types

A screen type is used to describe a viewport size range; it provides an opportunity to describe the parameters like name, max size of the screen type.

For example:

{
    name: 'screen-type',
    max: 1024
}

name

Type: String

Set name for screen type.

max

Type: Number

Set max viewport size for screen type

min

Type: Number

Set min viewport size for screen type

Events

viewport:change

Event Data: Object

Data Structure:

• type: Object

Current viewport screen type.

• width: Number

Current viewport width.
