Animate element to auto height with jQuery

Question

I want to animate a <div> from 200px to auto height. I can’t seem to make it work though. Does anyone know how?

Here’s the code:

$("div:first").click(function(){
  $("#first").animate({
    height: "auto"
  }, 1000 );
});

Answer 1

you can store it in a data attribute.

$('.colapsable').each(function(){
    $(this).attr('data-oheight',$(this).height());
    $(this).height(100);
});

$('.colapsable h2:first-child').click(function(){
    $(this).parent('.colapsable').animate({
            height: $(this).parent('.colapsible').data('oheight')
        },500);
    }
});

Toggle slide (Box9's answer expanded)

$("#click-me").click(function() {
  var el = $('#first'),
  curHeight = el.height(),
  autoHeight = el.css('height', 'auto').height(),
  finHeight = $('#first').data('click') == 1 ? "20px" : autoHeight;
  $('#first').data('click', $(this).data('click') == 1 ? false : true);
  el.height(curHeight).animate({height: finHeight});
});

#first {width: 100%;height: 20px;overflow:hidden;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="first">
  <div id="click-me">Lorem ipsum dolor sit amet, consectetur adipiscing elit</div>

</div>

You can make Liquinaut's answer responsive to window size changes by adding a callback that sets the height back to auto.

$("#first").animate({height: $("#first").get(0).scrollHeight}, 1000, function() {$("#first").css({height: "auto"});});

Answer 4

this is working and it is simplier then solutions before:

CSS:

#container{
  height:143px;  
}

.max{
  height: auto;
  min-height: 143px;
}

JS:

$(document).ready(function() {
    $("#container").click(function() {      
        if($(this).hasClass("max")) {
            $(this).removeClass("max");
        } else {
            $(this).addClass("max");
        }

    })
});

Note: This solution requires jQuery UI

you can always do this:

jQuery.fn.animateAuto = function(prop, speed, callback){
var elem, height, width;
return this.each(function(i, el){
    el = jQuery(el), elem = el.clone().css({"height":"auto","width":"auto"}).appendTo("body");
    height = elem.css("height"),
    width = elem.css("width"),
    elem.remove();

    if(prop === "height")
        el.animate({"height":height}, speed, callback);
    else if(prop === "width")
        el.animate({"width":width}, speed, callback);  
    else if(prop === "both")
        el.animate({"width":width,"height":height}, speed, callback);
});  
}

Here's one that works with BORDER-BOX ...

Hi guys. Here is a jQuery plugin I wrote to do the same, but also account for the height differences that will occur when you have box-sizing set to border-box.

I also included a "yShrinkOut" plugin that hides the element by shrinking it along the y-axis.

---

// -------------------------------------------------------------------
// Function to show an object by allowing it to grow to the given height value.
// -------------------------------------------------------------------
$.fn.yGrowIn = function (growTo, duration, whenComplete) {

    var f = whenComplete || function () { }, // default function is empty
        obj = this,
        h = growTo || 'calc', // default is to calculate height
        bbox = (obj.css('box-sizing') == 'border-box'), // check box-sizing
        d = duration || 200; // default duration is 200 ms

    obj.css('height', '0px').removeClass('hidden invisible');
    var padTop = 0 + parseInt(getComputedStyle(obj[0], null).paddingTop), // get the starting padding-top
        padBottom = 0 + parseInt(getComputedStyle(obj[0], null).paddingBottom), // get the starting padding-bottom
        padLeft = 0 + parseInt(getComputedStyle(obj[0], null).paddingLeft), // get the starting padding-left
        padRight = 0 + parseInt(getComputedStyle(obj[0], null).paddingRight); // get the starting padding-right
    obj.css('padding-top', '0px').css('padding-bottom', '0px'); // Set the padding to 0;

    // If no height was given, then calculate what the height should be.
    if(h=='calc'){ 
        var p = obj.css('position'); // get the starting object "position" style. 
        obj.css('opacity', '0'); // Set the opacity to 0 so the next actions aren't seen.
        var cssW = obj.css('width') || 'auto'; // get the CSS width if it exists.
        var w = parseInt(getComputedStyle(obj[0], null).width || 0) // calculate the computed inner-width with regard to box-sizing.
            + (!bbox ? parseInt((getComputedStyle(obj[0], null).borderRightWidth || 0)) : 0) // remove these values if using border-box.
            + (!bbox ? parseInt((getComputedStyle(obj[0], null).borderLeftWidth || 0)) : 0) // remove these values if using border-box.
            + (!bbox ? (padLeft + padRight) : 0); // remove these values if using border-box.
        obj.css('position', 'fixed'); // remove the object from the flow of the document.
        obj.css('width', w); // make sure the width remains the same. This prevents content from throwing off the height.
        obj.css('height', 'auto'); // set the height to auto for calculation.
        h = parseInt(0); // calculate the auto-height
        h += obj[0].clientHeight // calculate the computed height with regard to box-sizing.
            + (bbox ? parseInt((getComputedStyle(obj[0], null).borderTopWidth || 0)) : 0) // add these values if using border-box.
            + (bbox ? parseInt((getComputedStyle(obj[0], null).borderBottomWidth || 0)) : 0) // add these values if using border-box.
            + (bbox ? (padTop + padBottom) : 0); // add these values if using border-box.
        obj.css('height', '0px').css('position', p).css('opacity','1'); // reset the height, position, and opacity.
    };

    // animate the box. 
    //  Note: the actual duration of the animation will change depending on the box-sizing.
    //      e.g., the duration will be shorter when using padding and borders in box-sizing because
    //      the animation thread is growing (or shrinking) all three components simultaneously.
    //      This can be avoided by retrieving the calculated "duration per pixel" based on the box-sizing type,
    //      but it really isn't worth the effort.
    obj.animate({ 'height': h, 'padding-top': padTop, 'padding-bottom': padBottom }, d, 'linear', (f)());
};

// -------------------------------------------------------------------
// Function to hide an object by shrinking its height to zero.
// -------------------------------------------------------------------
$.fn.yShrinkOut = function (d,whenComplete) {
    var f = whenComplete || function () { },
        obj = this,
        padTop = 0 + parseInt(getComputedStyle(obj[0], null).paddingTop),
        padBottom = 0 + parseInt(getComputedStyle(obj[0], null).paddingBottom),
        begHeight = 0 + parseInt(obj.css('height'));

    obj.animate({ 'height': '0px', 'padding-top': 0, 'padding-bottom': 0 }, d, 'linear', function () {
            obj.addClass('hidden')
                .css('height', 0)
                .css('padding-top', padTop)
                .css('padding-bottom', padBottom);
            (f)();
        });
};

Any of the parameters I used can be omitted or set to null in order to accept default values. The parameters I used:

• growTo: If you want to override all the calculations and set the CSS height to which the object will grow, use this parameter.
• duration: The duration of the animation (obviously).
• whenComplete: A function to run when the animation is complete.
