You can trigger the click of your reset button and clear the whole div in your document ready function. After this you can remove the class "selected" so its completely reset.
Like this
$(document).ready(function() {
$('select').multi({
search_placeholder: 'Search',
});
$('#tabReset').click(function() {
$('.selected-wrapper').empty();
$('a').removeClass('selected');
});
});

attach an event to reset button. empty the selected-wrapper and remove the selected class from non-selected-wrapper
$("button.alltabreset").click(function(){
$(".selected-wrapper").empty();
$(".item").removeClass("selected");
});

Get Bouncy Content Filter to run automatically

I'm using this awesome bouncy filter from Codyhouse but i can't for the life of me figure out how to make it run automatically i.e flip on its own and still accept user click events. The jsfiddle...Thanks.
jQuery(document).ready(function($) {
//wrap each one of your filter in a .cd-gallery-container
bouncy_filter($('.cd-gallery-container'));
function bouncy_filter($container) {
$container.each(function() {
var $this = $(this);
var filter_list_container = $this.children('.cd-filter'),
filter_values = filter_list_container.find('li:not(.placeholder) a'),
filter_list_placeholder = filter_list_container.find('.placeholder a'),
filter_list_placeholder_text = filter_list_placeholder.text(),
filter_list_placeholder_default_value = 'Select',
gallery_item_wrapper = $this.children('.cd-gallery').find('.cd-item-wrapper');
//store gallery items
var gallery_elements = {};
filter_values.each(function() {
var filter_type = $(this).data('type');
gallery_elements[filter_type] = gallery_item_wrapper.find('li[data-type="' + filter_type + '"]');
});
//detect click event
filter_list_container.on('click', function(event) {
event.preventDefault();
//detect which filter item was selected
var selected_filter = $(event.target).data('type');
//check if user has clicked the placeholder item (for mobile version)
if ($(event.target).is(filter_list_placeholder) || $(event.target).is(filter_list_container)) {
(filter_list_placeholder_default_value == filter_list_placeholder.text()) ? filter_list_placeholder.text(filter_list_placeholder_text): filter_list_placeholder.text(filter_list_placeholder_default_value);
filter_list_container.toggleClass('is-open');
//check if user has clicked a filter already selected
} else if (filter_list_placeholder.data('type') == selected_filter) {
filter_list_placeholder.text($(event.target).text());
filter_list_container.removeClass('is-open');
} else {
//close the dropdown (mobile version) and change placeholder text/data-type value
filter_list_container.removeClass('is-open');
filter_list_placeholder.text($(event.target).text()).data('type', selected_filter);
filter_list_placeholder_text = $(event.target).text();
//add class selected to the selected filter item
filter_values.removeClass('selected');
$(event.target).addClass('selected');
//give higher z-index to the gallery items selected by the filter
show_selected_items(gallery_elements[selected_filter]);
//rotate each item-wrapper of the gallery
//at the end of the animation hide the not-selected items in the gallery amd rotate back the item-wrappers
// fallback added for IE9
var is_explorer_9 = navigator.userAgent.indexOf('MSIE 9') > -1;
if (is_explorer_9) {
hide_not_selected_items(gallery_elements, selected_filter);
gallery_item_wrapper.removeClass('is-switched');
} else {
gallery_item_wrapper.addClass('is-switched').eq(0).one('webkitAnimationEnd oanimationend msAnimationEnd animationend', function() {
hide_not_selected_items(gallery_elements, selected_filter);
gallery_item_wrapper.removeClass('is-switched');
});
}
}
});
});
}
});
function show_selected_items(selected_elements) {
selected_elements.addClass('is-selected');
}
function hide_not_selected_items(gallery_containers, filter) {
$.each(gallery_containers, function(key, value) {
if (key != filter) {
$(this).removeClass('is-visible is-selected').addClass('is-hidden');
} else {
$(this).addClass('is-visible').removeClass('is-hidden is-selected');
}
});
}

I'm assuming by "make it run automatically" you're talking about triggering the content-selection animation programatically, rather than requiring a user click. One possible solution is to assign an id to the selection elements, and then register the click handler directly to those elements, rather than the parent filter_list_container. Then, you can use jQuery's trigger() method to simulate a click on the appropriate element.
Assign an id in the html like this:
<a id="green" href="#0">Green</a>
Then register the click handler like this:
$("#red, #green, #blue").on('click', function(event){ ... }
...and trigger like this:
$("#green").trigger("click");
Here's a JSfiddle with an example.

Javascript show div when all radio button is checked

I have a code that can show div everytime I click a radio button and it is working fine. The problem is I want all the radio button be checked and then the div will show.
Here is my code for 1 radio button
function showstuff(nxt){
document.getElementById(nxtb).style.display="block";
}
<input id="ny" name="ny" type="radio" onClick="document.getElementById('ny').checked =
true; showstuff('nxt');" />
<div id="nxtb">Next</div>
Thanks in advance

Here is a solution without an obtrusive JavaScript (that is onclick attributes):
/*
* Convert to array so we can use `forEach()` and `every()`
*/
function toArray(any) {
return Array.prototype.slice.call(any);
}
var observed = toArray(document.querySelectorAll('[data-observe]'));
var listened = [];
var result = document.querySelector('#result');
/*
* Gather all elements we want to listen for change:
* observed elements and their siblings with the same name
*/
observed.forEach(function (target) {
var siblings = toArray(document.querySelectorAll('[name=' + target.name +']'));
listened = listened.concat(siblings);
});
listened.forEach(function (radio) {
radio.addEventListener('change', function () {
var checked = observed.every(function (item) {
return item.checked;
});
checked ?
result.removeAttribute('hidden') :
result.setAttribute('hidden', 'true');
});
});

clearing radio input using jQuery

I have a bunch of radio buttons that are below. These radio buttons are part of a larger form and are optional, so If a user clicks on one, then decides he/she doesn't want the option selected, there is no way to undo this.
I was wondering if there was any jQuery etc, that, when clicking a link for example, clear any radio selection, based on the group name in the HTML?
Thanks

var group_name = "the_group_name";
// if jquery 1.6++
$(":radio[name='" + group_name + "']").prop('checked', false);
// prev than 1.6
// $(":radio[name='" + group_name + "']").attr('checked', false);
Working demo: http://jsfiddle.net/roberkules/66FYL/

var Custom = {
init: function() {
checkAllPrettyCheckboxes = function(caller, container){
// Find the label corresponding to each checkbox and click it
$(container).find('input[type=checkbox]:not(:checked)').each(function(){
if($.browser.msie){
$(this).attr('checked','checked');
}else{
$(this).trigger('click');
};
});
};
uncheckAllPrettyCheckboxes = function(caller, container){
// Find the label corresponding to each checkbox and unselect them
$(container).find('input[type=checkbox]:checked').each(function(){
$('label[for="'+$(this).attr('id')+'"]').trigger('click');
if($.browser.msie){
$(this).attr('checked','');
}else{
$(this).trigger('click');
};
});
};
I have created it in an init function, and adter then i called the init.
}
window.onload = Custom.init;

I have created a solution like roberkules' solution, except mine clears the radiobutton if you click the radiobutton itself while it's checked. Use this if you don't want to add an extra "Clear" button to your layout.
http://jsfiddle.net/P9zZQ/6/
// Requires JQuery 1.4+ (possibly earlier)
$(function () {
// Turn off a radiobutton if clicked again while on
var checkOff = function (event) {
var target = $(event.target);
if (target.is('label')) {
// deal with clicked label
if (target.attr('for')) {
// label has 'for' attribute
target = $('#' + target.attr('for'));
} else {
// label contains a radiobutton as a child
target = target.find('input[type=radio]');
}
}
if (target.is('input:checked[type=radio]')) {
event.preventDefault();
window.setTimeout(function () {
target.attr('checked', false);
}, 200);
}
}
// Find all radiobuttons and labels inside .radio-clearable containers
$(
'.radio-clearable input[type=radio], ' +
'.radio-clearable label').mousedown(function (event) {
// When clicked -- clear if it was checked
checkOff(event);
}).keydown(function (event) {
// When receiving space, escape, enter, del, or bksp -- clear if it was checked
if (event.which == 32 || event.which == 27 || event.which == 13 || which == 46 || which == 8) {
checkOff(event);
}
});
});
Usage: For any radiobutton you want to be clearable in this manner, wrap it in a container with class "radio-clearable".
The code is triggered by clicking or sending a key (Space, Escape, Enter, Del, BkSp) to the radiobutton element or to its label.

How to uncheck a radio button by clicking on it a second time

I have been searching in a lot of topics but I haven't found anything that really correspond to my problem :
I want to make radio buttons uncheckable (i.e. uncheck a radio button by clicking on it when it's already checked).
I found some solutions using a hidden radio button as a temporary comparison object but this doesn't fits to my existing context, so I would like to do the same without another radio button.
I tried to simply test and change the status/value of the radio button on "onclick" event but it hasn't been very successfull...
Thanks in advance,
Clem.

That's not what radio buttons are. If you try to make this work, you will just confuse your users.
If you want something that can be checked and then unchecked, use a checkbox. Radio buttons are for selecting exactly one of some set of options.

better so:
onclick="
var isChecked = $(this).attr('is_che');
if (isChecked) {
$(this).removeAttr('checked');
$(this).removeAttr('is_che');
}
else {
$(this).attr('checked', 'checked');
$(this).attr('is_che', 'true');
}"

I know this sort of action is non-standard for radio buttons, but the poster requested the functionality. The following is code that I've used in the past. I've found it not to be the most optimized (assuming a large # of radio buttons), but I also haven't taken the time to do that optimization.
// Allow for radio button unchecking
$(function(){
var allRadios = $('input[type=radio]')
var radioChecked;
var setCurrent = function(e) {
var obj = e.target;
radioChecked = $(obj).attr('checked');
}
var setCheck = function(e) {
if (e.type == 'keypress' && e.charCode != 32) {
return false;
}
var obj = e.target;
if (radioChecked) {
$(obj).attr('checked', false);
} else {
$(obj).attr('checked', true);
}
}
$.each(allRadios, function(i, val) {
var label = $('label[for=' + $(this).attr("id") + ']');
$(this).bind('mousedown keydown', function(e){
setCurrent(e);
});
label.bind('mousedown keydown', function(e){
e.target = $('#' + $(this).attr("for"));
setCurrent(e);
});
$(this).bind('click', function(e){
setCheck(e);
});
});
});
