Close Bootstrap Dropdown after link click

I have a bootstrap dropdown menu below. It has a link in it hooked up to a knockout.js binding, that returns false because I don't want the # tag to be sent to the browser URL. However, doing this doesn't close the dropdown menu when I click the link. Any way around this?

HTML

<div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown" data-bind="enable: !noResults()"><i class="icon-download-alt" ></i> Export <span class="icon-caret-down"></span></button>

    <ul class="dropdown-menu">
        @foreach(var exportUrl in Model.ExportUrls)
        {
            <li>
                <a href="#" data-bind="disable: noResults(), download: { url: '@exportUrl.Value', data: data }"><img src="/Content/less/images/img/@(exportUrl.Key.ToString().ToLower()).png" alt="@exportUrl.Key.GetDisplayName()"/> @exportUrl.Key.GetDisplayName()</a>
            </li>
        }
    </ul>
</div>

knockut.js binding

ko.bindingHandlers.download = {
    init: function (element, valueAccessor) {

        var value = ko.utils.unwrapObservable(valueAccessor()),
            id = 'download-iframe-container',
            iframe;

        $(element).unbind('click').bind('click', function () {

            iframe = document.getElementById(id);

            if (!iframe) {
                iframe = document.createElement("iframe");
                iframe.id = id;
                iframe.style.display = "none";
            }

            if (value.data) {
                iframe.src = value.url + (value.url.indexOf('?') > 0 ? '&' : '?') + $.param(ko.mapping.toJS(value.data));
            } else {
                iframe.src = value.url;
            }

            document.body.appendChild(iframe);

            return false;
        });
    }
};

Give your links a class (e.g. download):

<a href="#" class="download" data-bind="disable: noResults()....

And your dropdown an id (e.g. dlDropDown):

<button class="btn dropdown-toggle" id="dlDropDown" data-toggle="dropdown" data-bind="enable: !noResults()">

And then add the following event handler:

$("a.download").click(function() {
   $("#dlDropDown").dropdown("toggle");
});

This will actually work with your existing bootstrap markup without having to add any new classes or ids. Hopefully this is helpful to someone else just looking to drop a solution in without changing anything existing.

$(".dropdown-menu a").click(function() {
	$(this).closest(".dropdown-menu").prev().dropdown("toggle");
});

This can be achieved with bootstraps own CSS class dropdown-toggle

Just add that class to your link elements like so: <a class='dropdown-toggle'></a> and it will toggle the dropdown.

I think this will close all dropdowns and expanded navmenus on the page:

$('.in,.open').removeClass('in open');

I unfortunately had no success using .dropdown('toggle') as suggested above...

What did work however was applying bootstrap's dropdown button data attributes to it's own dropdown links:

<button type="button" data-toggle="collapse" data-target=".navbar-collapse" class="navbar-toggle navbar-btn">

...

<ul class="nav navbar-nav">
  <li><a href="#about" class="scroll-to" data-toggle="collapse" data-target=".navbar-collapse">About</a></li>

All I did was add the data-toggle="collapse" and data-target=".navbar-collapse" to each dropdown nav link.

No additional css or js and it worked like a charm :)

Using event.preventDefault() instead of return false does the trick.

Change your code to:

$(element).unbind('click').bind('click', function(e) {
  e.preventDefault();

  // ...

  return true; // or just remove the return clause
});

Simply change the href="#" to href="javscript:void(0);" and then return true in your click event (instead of false).

If you've got an event parameter just do:

$(element).unbind('click').bind('click', function (event)
{
    event.preventDefault();
    return true;
});

A cleaner solution, to keep the dropdown functionality and get what you are looking for.

$("body").on('click', function (e) {
     if (!$(e.target).hasClass("open") && $(e.target).parents(".btn-group.open").length == 0)
         $(this).find(".btn-group.open a").trigger("click");
});

the best answer will be is to perform click so it will act the same as the user click the mouse to hide the drop-down menu, to do this add this snap code to your page:

<script>
    $(document).ready(function () {
        $("li.dropdown ul.dropdown-menu li").click(function (event) {
            event.toElement.parentElement.click();
        })
    })
</script>

you can also add a transparent mask to block any other unwanted click when dropdown is open:

   OnDomReadyHeaderItem.forScript("$('.dropdown').on('shown.bs.dropdown', function (e) { $(this).append('<span id=\"transparent-mask\"></span>')})"));
    
   OnDomReadyHeaderItem.forScript("$('.dropdown').on('hidden.bs.dropdown', function (e) { $('#transparent-mask').remove()})"));

with the mask:

.dropdown.open #transparent-mask{
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    display: block;
    margin: auto;
    height: initial;
    z-index: 1000 !important;
}

when click on menu then the nav will be close this is the easy way to do it using jquery onclick="$('#mobile-menu').removeClass('mm-menu_opened');"
