How can I show a hidden DIV for a selection included with others?

I have a javascript file that when called, checks to see if a particular option is selected on a form. The form allows for multiple selections before being submitted. When a particular item is selected within the given choices it shows a hidden menu. In this case with "audits" I am able to show the hidden menu fine when just "audits" is selected from the list. However, I'm having much difficulty in figuring out how to get the menu to show when "audits" would be selected/highlighted with others. Eg: I had audits, services, someotheroption
Below you can see the code I'm currently using and that's working only when the single item is selected. Any guidance would be much appreciated.
function toggleFields(){
function toggleFields(){
if ($("#installations").val() == "audits"){
$("#dbcredentialsfield").show();
}
else
$("#dbcredentialsfield").hide();
}

Using the code you have so far, I assume you probably want something like this:
$('#installations').on('change', function(){
$("#dbcredentialsfield").toggle($(this).val() == 'audits');
});
This says; when the select element (assuming your dropdown has the id of installations) changes, toggle the visibility of the element with id dbcredentialsfield depending on if the value of the select is audits or not.

Change content on click of button in jquery

So my scenario goes like this:
I have 3 kind on item to show in div. There are three buttons on top of div and when user click any of the button items corresponding to that items are shown.
Items comes from backend and I am getting all the items loaded on page load as I also need them some where else also within same context.
Currently I am following show hide approach for the same .What I want to know is can there be any other approach that can be better then this in terms of code optimisation. User can also edit /add./remove item?
Here is my fiddle
$(document).ready(function(){
console.log($('.toggleItems'));
$('.toggleItems').click(function(){
$('.containers').hide();
var identifier = $(this).data('identifier');
console.log(identifier);
$('#'+identifier).show();
});
})

First order by items then use accordion jquery

When tableDnD is disabled it leaves residual css and I can't clear the css

tableDnD (table Drag and Drop) is a jQuery plugin I'm using to be able to re-order rows in my html table. It's a pretty cool library, but the fact that you can click, drag, and drop rows -- disables the ability to select that row by clicking -- it thinks you might be starting a drag and drop, or doing a 0-distance drag.
So you can view my example here, and see what I'm talking about -- http://jsfiddle.net/du31ufts/5/
It starts off as disabled, so enable the row re-ordering and see the library. Then, try to select just one row in the middle. The only way the blue highlighting indicating selection shows up is if you click outside the bounds of the table, and thus you would only be able to select starting from the bottom or top, and not be able to select one row at a time. I need to select these rows to be able to copy-paste these rows into excel.
I've tried looking into the library itself and detaching $('__dragtable_disable_text_selection__'), I've tried jquerys removeAttr for unselectable, I've tried
$('.dragtable-sortable').attr('-moz-user-select', 'none');
Nothing is re-enabling my ability to be able to click and select single rows. I'd like to do this without modifying tableDnD functions.
Which CSS properties could be affecting my ability to select table rows?

Create a textarea somewhere with ID #spot.
Use this code to extract data on click from a row and select it. Its delimited by tab so it should be pastable into excel easily.
$('tr').click(function(){
var copyContent = "";
$(this).children('td').each(function(){
copyContent = copyContent+$(this).text()+"\t";
});
$('#spot').val(copyContent);
$('#spot').select();
});

I asked about this on github and got an answer: It did require modification of the library. Specifically, replacing the if block starting at line 207 of the fiddle in this question with this
if (!$(this).hasClass("nodrag")) {
if (e.target.tagName == "TD") {
$.tableDnD.initialiseDrag(this, table, this, e, config);
return false;
}
}
modified fiddle. Thank you tschqr

Multy-filter page with transitions - Isotope & Quicksand JS problems

(note: edited since I've just realized the question are somehow correlated, at least in my mind!)
I want to create a multi-filter page in which the result will be animated...
I'm trying with 2 different plugin (quicksand and Isotope) and with both solution I'm having problems...
---ISOTOPE--- (original)
With Isotope I need to filter data based on active class, or based on IDs of filters, which I've already stored in JS, does anyone know how can I do that?
I set up a page with 2 different filter like 'color' (red, blue, orange...) and 'type' (square, round...)
I already have a Javascript that assign class active to the 2 filtering lu based on selection, if all color are selected shift the 'active' class to 'all', and more than one sub-filter can be activated. And this also save the list of the id of the active li items in a string for color filter and another string for shape filter
I also already set up the page like the combination filter Isotope demo at this link: http://isotope.metafizzy.co/demos/combination-filters.html and it is working fine but doesn't allow to select more than one sub-filter at the same time.
I saw the demo at this link http://fiddle.jshell.net/desandro/JB45z/ with filtering combination, but it is based on radio button that I'd like to avoid.
I'm not sure if what I'm trying to do is easy or not... is like, how to tell to Isotope to filter based on the sub-filter that have active class or based on the sum of the li with the ID saved in my two string?
Thanks for any help, as you can easily understand I'm not skilled in js at all and english is not my first language!
--- QUICKSAND --- (edited)
I've just realized that I didn't explain why I stored the IDs of the selected items in the js string. And this is also about the different js question.
I was trying to set up the same system with Quicksand instead of Isotope.
But since quicksand need to have a starting li and a destination li to display the animation I set up the js to pass an array to a different temporary php page that use the array to display a destination li.
All until here is working fine but I'm not able to get back the li data in the original page to let Quicksand perform the animation. The last part of my js appear to have problems that I'm not able to fix (too many days trying with no success), the last part of the js is:
$.post( 'destination_li_filtered.php', {
colorString,
shapeString,
$('#ids').attr('val')
},
function(data) { // should contains the resulting data from the request (?)
$('.list').quicksand( $(data).find('li'),
{ adjustHeight: 'auto' },
function() {
callbackCode();
}
);
e.preventDefault();
});
the external page destination-li-filtered is displaying the results but the original page is not able to take back the data...
Obviously I need to set op the page with isotope or quicksand, not both.
but I'm also wondering witch is the best plugin to display 100's of results with about 20 filters (without considering the combinations). And of course, which is the easiest to use!

You should see the radio button and the change in view as separate things.
It's a common misconception that you should store all your state in the DOM (ie. which checkbox is checked). The DOM is a view, you don't keep state in a view.
You should have a state that lives in your JavaScript.
Like:
var state = "all_selected"; // green, red, blue
Then, when you check the radio button, it will set the appropriate state and update the list (show/hide elements based on state).
This allows you to make any control you want, be it a radio button, a checkbox or something completely custom.

Get the value of a Drop list while hovering the options without clicking with JS

How can I get the value of a Drop list while hovering the options with the mouse without clicking (selecting) using JS or jQuery?
Ex.
List of Stuff
-Dog
-Cat
-Bird
When I move my mouse around the options of the droplist, it will tell me that my item is being highligted.

This isn't possible with standard selects, but if you need the desired effect badly enough you can create your own select components and back them with hidden inputs.
