How to scroll a select list with JavaScript or jQuery?

Question

I have a select tag:

           <select size="3"> 
           <option value="1">value 1</option> 
           <option value="2">value 2</option> 
           <option value="3">value 3</option> 
           <option value="4">value 4</option> 
           <option value="5">value 5</option> 
           <option value="6">value 6</option> 
           <select>

Now it displays first 3 options, how can I scroll to see elements from 3-5 or 4-6 using jQuery or pure JavaScript?

In Chrome, a `select` scrollbox will automatically scroll to highlight a selected item (but no further). You can use JavaScript to select and then de-select a particular `option` to force scrolling. — Blazemonger, Nov 22 '13 at 17:33
For me, with Chrome 41 on Linux, the select will NOT automatically scroll if it's display:none, or a parent is display:none, during page load. Even if the css style is set to display:something (e.g. parent set display:block) during body's onload it doesn't scroll properly. Re-setting the selectedIndex to itself after setting, e.g. display:block on relevant parent, caused the scrolling to take place. — dmansfield, Apr 06 '15 at 20:17

.scrollTop() may work:

$('select').scrollTop(30);

And you can scroll to a particular element using this:

var $s = $('select');

var optionTop = $s.find('[value="3"]').offset().top;
var selectTop = $s.offset().top;

$s.scrollTop($s.scrollTop() + (optionTop - selectTop));

Try it here: http://jsfiddle.net/kj9p4/

Note: does not work in Chrome.

Thats work, now the worst part :) to calculate how much pixels to scroll. – Zemzela Aug 26 '11 at 14:07
I've added the code and jsfiddle for how to scroll to a particular element; I've tested this in firefox – Arnaud Le Blanc Aug 26 '11 at 14:08

Did you try it in Chrome? Doesn't work for me there. Seems to have to do with getting the offset of the option element. – user113716 Aug 26 '11 at 14:19
Also doesn't work in Safari 6. Calling offset() on the option returns 0 for top and left. – giskard22 Feb 25 '14 at 05:44
Works fine in chrome Version 49.0.2623.87 m – ZalemCitizen Apr 01 '16 at 16:32

 $("select").scrollTop($("select").find("option[value=4]").offset().top);

Just set the appropriate selectors for select element and values inside

works fine for me, but you need to subtract the offset of the select itself i.e. - $('select').offset().top – FtLie Sep 19 '15 at 22:12

I built this extension which is a more appropriated solution to this problem. It's flexible and reusable and it's built on top of jQuery. http://jsfiddle.net/db86eu91/4/

$.fn.ScrollToValue = function(target){
    var $select = $(this);
    if (!$select.length) return;

    var value = target;

    //how many pixels is the select list scrolled from the moment we run this code???
    var distanceScrolledFromTop = $select.scrollTop();
    //how many pixels separate the top of the page from the <select> element that we pretend to manipulate
    var offsetSelect = $select.offset().top;
    //assuming a offset().top of 0 on our list how many pixels separate our target option from the top of the page? 
    var offsetElement = $select.find('[value=' + value + ']').offset().top + distanceScrolledFromTop;

    //Because the offset of our element is always bigger than the offset of our select box, we must subtract the offset of our target element by the offset of our list. That's it
    $select.scrollTop(offsetElement - offsetSelect);
}

})();

You will have to watch out if you are doing this from say a `bootstrap modal` since timing will be an issue. Make this call in the `shown` event. — Grandizer, Jul 14 '17 at 19:49

This is coffescript using jquery, (coffeescript translates directly into javascript)

exports.mylist_scroll_to  = (value) ->
    element = $("#mylist")[0]
    item_height = element.scrollHeight/element.length
    $("#mylist").scrollTop(item_height*(element.selectedIndex))

Or you can just use focus().

$("select").find("option[value=4]").focus();
$('select option[value="banana"]').focus();

To scroll to the top of the list: `$('select option:first').focus()` – Glen Little Jul 04 '16 at 19:54

Although its from 2011, I was facing a large problem with Primefaces, as I use listboxes extensively.

When I load items from a database in order to populate many listboxes, they werent scrolled by default.

I fixed this by creating a JavaScript function.

//This function is used in primefaces listboxes with many items (which doesnt use the HTML tag 'option value="XXX" selected'). So, by default, if the current selected item is out of view, like near the bottom end, the scroll doesnt execute at all.

In order to use the function below, you need to put a javascript call in your listbox, like oncomplete="autoScrollListBox('#form\:lixtboxID');"

You can customize this function to traverse/loop through other lists, like dataTables or customized ui-******-***** names (just change them below).

function autoScrollListBox(id) {
    var listContainer=id+'  .ui-selectlistbox-listcontainer';
    var listContainerList=id+'  .ui-selectlistbox-listcontainer  .ui-selectlistbox-list';

    var listTop = $(listContainerList).offset().top;
    var selectedContainer=id+ ' .ui-state-highlight';
    var selectedOptionTop =$(id+' .ui-state-highlight').offset().top;
   $(listContainer).animate( {scrollTop:selectedOptionTop-listTop});
    }

You can use the val() function on your list. Use last item from the ones you want to display as the argument

$("#foo").val('5');

This will show 3-5.

Here is a workaround to this

Working demo

Code

$(function(){
    //Select the last option in the range which you want to scroll to
    var lastOption = $("select").find("option[value=5]")
        //Store the selection state
        var isSelected = lastOption.is(":selected");

        lastOption.attr("selected", true)//This will scroll to the option
            .attr("selected", isSelected); //Restore the selection state
});
