Owl Carousel 2 - autoHeight (multiple items)

Question

At the moment the Owl Carousel autoHeight works only with 1 item on screen. Their plan is to calculate all visible items and change height according to highest item.

I work around this problem by calling the .active classes on the visible items, and give the invisible items a small height. Is there already a more elegant solution?

$('.owl-carousel').owlCarousel({
loop: true,
items: 3,
margin: 1,
autoHeight: true,
});

Fiddle

Any Ideas? Thanks!

Solution 1

I'm not sure if anyone is still looking for solutions for this problem in 2020, but after trying a lot of things that didn't work, I found a very simple one. It's all about setting no height to the item that's not active.

Like so:

.owl-item {height: 0;}    
.owl-item.active {height: auto;}

It's elegant and no javascript is needed. You can even play with transitions to set some cool animations.

I hope I have helped someone here.

PS: To use this method, keep autoHeight: false ... otherwise the carousel height will be set to 0 by the library

Solution 2

I solved it via the internal API using several events calling the same autoHeight-function.

Fiddle

The jQuery-Part:

$('.owl-carousel').owlCarousel({
    loop: true,
    items: 3,
    margin: 1,
    autoHeight: true,
    onInitialized: setOwlStageHeight,
    onResized: setOwlStageHeight,
    onTranslated: setOwlStageHeight
});
function setOwlStageHeight(event) {
    var maxHeight = 0;
    $('.owl-item.active').each(function () { // LOOP THROUGH ACTIVE ITEMS
        var thisHeight = parseInt( $(this).height() );
        maxHeight=(maxHeight>=thisHeight?maxHeight:thisHeight);
    });
    $('.owl-carousel').css('height', maxHeight );
    $('.owl-stage-outer').css('height', maxHeight ); // CORRECT DRAG-AREA SO BUTTONS ARE CLICKABLE
}

For enabling the height-animation I added the following CSS:

.owl-carousel,
.owl-stage-outer { transition: height 500ms ease-in-out 0s; }

Hope it helps.

Solution 3

I used flex to solve this issue:

 .owl-stage {
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;

    -webkit-flex-wrap: wrap;
    -ms-flex-wrap: wrap;
    flex-wrap: wrap;
}

above code for owl-stage and below for owl-item class:

.owl-item{
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
    height: auto !important;
}

I hope this reply help every body that have this issue.

Thanks for your great help!! It works nicely, when the item has a given height. Is it possible to scale the stageHeight, according to dynamic item heights? And is there a way to initialize the stageHeight with the height of the first item (on page load)? jsfiddle.net/Schakelen/y18074c0

I don´t understand as your Fiddle already works with dynamic item heights, I cannot find any fixed heights. And yes, you can init the stageHeight by the first item´s height by using the jQuery :first-selector. https://jsfiddle.net/y18074c0/5/

brilliant! worth mentioning to keep autoHeight: false, otherwise the height of all items will be 0.

[usernotnull]

can you show an example of how to add transition animation please?
