Let’s look on list of all available parameters:
| Parameter | Type | Default | Description |
|---|---|---|---|
| init | boolean | true | Whether Swiper should be initialised automatically when you create an instance. If disabled, then you need to init it manually by calling mySwiper.init() |
| initialSlide | number | 0 | Index number of initial slide. |
| direction | string | ‘horizontal’ | Could be ‘horizontal’ or ‘vertical’ (for vertical slider). |
| speed | number | 300 | Duration of transition between slides (in ms) |
| setWrapperSize | boolean | false | Enabled this option and plugin will set width/height on swiper wrapper equal to total size of all slides. Mostly should be used as compatibility fallback option for browser that don’t support flexbox layout well |
| virtualTranslate | boolean | false | Enabled this option and swiper will be operated as usual except it will not move, real translate values on wrapper will not be set. Useful when you may need to create custom slide transition |
| width | number | Swiper width (in px). Parameter allows to force Swiper width. Useful only if you initialize Swiper when it is hidden.Setting this parameter will make Swiper not responsive | |
| height | number | Swiper height (in px). Parameter allows to force Swiper height. Useful only if you initialize Swiper when it is hidden.Setting this parameter will make Swiper not responsive | |
| autoHeight | boolean | false | Set to true and slider wrapper will adopt its height to the height of the currently active slide |
| roundLengths | boolean | false | Set to true to round values of slides width and height to prevent blurry texts on usual resolution screens (if you have such) |
| nested | boolean | false | Set to true on nested Swiper for correct touch events interception. Use only on nested swipers that use same direction as the parent one |
| uniqueNavElements | boolean | true | If enabled (by default) and navigation elements’ parameters passed as a string (like ".pagination") then Swiper will look for such elements through child elements first. Applies for pagination, prev/next buttons and scrollbar elements |
| effect | string | ‘slide’ | Tranisition effect. Could be “slide”, “fade”, “cube”, “coverflow” or “flip” |
| runCallbacksOnInit | boolean | true | Fire [Transition/SlideChange][Start/End] events on swiper initialization. Such events will be fired on initialization in case of your initialSlide is not 0, or you use loop mode |
| watchOverflow | boolean | false | When enabled Swiper will be disabled and hide navigation buttons on case there are not enough slides for sliding |
| on | object | Register event handlers | |
| Slides grid | |||
| spaceBetween | number | 0 | Distance between slides in px. |
| slidesPerView | number or ‘auto’ | 1 | Number of slides per view (slides visible at the same time on slider’s container).If you use it with “auto” value and along with loop: true then you need to specify loopedSlides parameter with amount of slides to loop (duplicate)slidesPerView: ‘auto’ is currently not compatible with multirow mode, when slidesPerColumn > 1 |
| slidesPerColumn | number | 1 | Number of slides per column, for multirow layoutslidesPerColumn > 1 is currently not compatible with loop mode (loop: true) |
| slidesPerColumnFill | string | ‘column’ | Could be ‘column’ or ‘row’. Defines how slides should fill rows, by column or by row |
| slidesPerGroup | number | 1 | Set numbers of slides to define and enable group sliding. Useful to use with slidesPerView > 1 |
| centeredSlides | boolean | false | If true, then active slide will be centered, not always on the left side. |

| longSwipesMs | number | 300 | Minimal duration (in ms) to trigger swipe to next/previous slide during long swipes |
| followFinger | boolean | true | If disabled, then slider will be animated only when you release it, it will not move while you hold your finger on it |
| allowTouchMove | boolean | true | If false, then the only way to switch the slide is use of external API functions like slidePrev or slideNext |
| threshold | number | 0 | Threshold value in px. If “touch distance” will be lower than this value then swiper will not move |
| touchMoveStopPropagation | boolean | true | If enabled, then propagation of “touchmove” will be stopped |
| iOSEdgeSwipeDetection | boolean | false | Enable to release Swiper events for swipe-to-go-back work in iOS UIWebView |

| touchReleaseOnEdges | boolean | false | Enable to release touch events on slider edge position (beginning, end) to allow for further page scrolling |
| passiveListeners | boolean | true | Passive event listeners will be used by default where possible to improve scrolling performance on mobile devices. But if you need to use `e.preventDefault` and you have conflict with it, then you should disable this parameter |
| Touch Resistance | |||

| Loop | |||
| loop | boolean | false | Set to true to enable continuous loop modeIf you use it along with slidesPerView: 'auto' then you need to specify loopedSlides parameter with amount of slides to loop (duplicate)Also, because of nature of how the loop mode works, it will add duplicated slides. Such duplicated classes will have additional classes:swiper-slide-duplicate – represents duplicated slideswiper-slide-duplicate-active – represents slide duplicated to the currently active slideswiper-slide-duplicate-next – represents slide duplicated to the slide next to activeswiper-slide-duplicate-prev – represents slide duplicated to the slide previous to active |
| loopAdditionalSlides | number | 0 | Addition number of slides that will be cloned after creating of loop |
| loopedSlides | number | null | If you use slidesPerView:'auto' with loop mode you should tell to Swiper how many slides it should loop (duplicate) using this parameter |
| loopFillGroupWithBlank | boolean | false | Enable and loop mode will fill groups with insufficient number of slides with blank slides. Good to be used with slidesPerGroup parameter |
| Breakpoints | |||
| breakpoints | object | Allows to set different parameter for different responsive breakpoints (screen sizes). Not all parameters can be changed in breakpoints, only those which are not required different layout and logic, like slidesPerView, slidesPerGroup, spaceBetween. Such parameters like slidesPerColumn, loop, direction, effect won’t work. For example:var swiper = new Swiper('.swiper-container', { // Default parameters slidesPerView: 4, spaceBetween: 40, // Responsive breakpoints breakpoints: { // when window width is <= 320px 320: { slidesPerView: 1, spaceBetween: 10 }, // when window width is <= 480px 480: { slidesPerView: 2, spaceBetween: 20 }, // when window width is <= 640px 640: { slidesPerView: 3, spaceBetween: 30 } } }) | |
