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

jQuery toggle a box inside a box

Trying to build a guestbook with some jQuery features..
Now when im clicking at the "Post"box it appears a new box with the name "MenuBox" (This box is always hidden) i got the toggle part to work ALMOST.
The meaning of the MenuBox, is that it should show over the PostBox with a delete button so they can delete the post.
But now when i try to toggle it, it toggles all the boxes, is there a possible way of like making $("$(this) .MenuBox").click(
Anyone got any clue?
Sorry if the explanation is bad..

Provided that .MenuBox is a child of $(this):
$(this).find('.MenuBox').click(...);

jCarousel with keyboard : wrong focus using the tab key

I'm using the 0.3 version of the jQuery jCarousel script to display three carousels on the webpage I'm working on. Those three carousels work just fine.
The trouble is : you can't use them properly using the keyboard.
If you tab through the page, the focus goes to the first link of the first item in the carousel, even if this item is not visible ! (For example : click on a "next" link in one of the carousels, then use the tab key to browse : the focus will go to a link which is not visible inside of the carousel).
If you keep using the "tab" key, the focus will successively go to all the links of all the items in the carousel.
Instead of that : the focus should go to the first link of the first visible item ; then, if the last link of the last visible item is reached, then the focus should go out of the carousel (the next link outside of it, in fact).
A solution could be to use tabindex... but some parts of the page are shared with other pages of the website, so I just can't use tabindex in all the links of all my pages...
Instead of that, I had tried things like this :
$("#carousel-editos li a").focusin(function () {
$("#carousel-editos li.jcarousel-item-first .post-title a").focus();
return false;
});
but then it prevents any further use of the "tab" key...
I hope this is clear... Thanx for any help !

I think you need a combination of the answers that you've already provided. It seems like you should be able to use Javascript to dynamically set tabindex attributes on the HTML that you need to be tabbable (heh, new word). I'm thinking of something like this:
On page load, find all visible items in the carousel. Use jQuery to set the tabindex property for each item that you want in the tab cycle.
Assign tabindex properties to all other links on the page that you want to cycle through.
Add some jQuery to modify the tabindex attributes when the user changes the items in the carousel (click the next/prev buttons).
It would be much easier to help you if you made a simplified example in jsFiddle.

On the carousel createEnd and scrollEnd functions you can reset the contents of .jCarousel so that only the visible carousel items are "tabbable". I have done that in my code as follows:
var bannerSlider_scrollEnd = function(event, carousel) {
var $carousel = carousel.element(),
$items = carousel.items(),
$bannerContent,
$visibleItemsContent = carousel.visible().find('.bannerContent');
$items.each(function (index) {
$bannerContent = $(this).find('.bannerContent');
disableTabbing($bannerContent);
});
reenableTabbing($visibleItemsContent);
$visibleItemsContent.find(':focusable').eq(0).focus();
};
The disableTabbing($container) and reenableTabbing($container) lines refer to helper functions I coded into my site which basically find all :focusable elements in a given container and set the tabindex to "-1", then "0" respectively.
After this processes, users will be left tabbing only through visible carousel items instead of all carousel items.

JQuery show hide with unordered list: need to add dynamic text / hide function

I have an unordered list where I hide any additional list items if more than 3. After that I invoke a JQuery function that puts in a "show more" link at the bottom and toggles any additional list items to show.
However, I'm a bit stuck, I'd like to convert the show link to "Hide" once all list items are showing and clicking on that then hides the additional list items and then the link changes back to "Show more..." again.
Here is the code I have so far that works to expand and show the additional list items.
$('ul li:gt('+index+')').hide();
$('ul').append('<li class="more">Show more...</li>');
$('ul li.more a').click(function() {
$('ul li.more a').remove();
$('ul li:gt('+index+')').show();
});
Note I am not stuck on this code, if there is a better way do implement the entire show / hide code, that's fine.
I wrote a fiddle with the code I have so far.

Here jquery toggle() function comes in handy - you can attach to event handlers that will be called every other time element is clicked. Use text() to change text of the link (which should't be a link if you don't plan a fallback - use span instead)
Updated fiddle.

There you go sir :)
Fixed and running well!

jquery selector problem in hierarchical expanding/collapsing tree

I'm trying to build a screen that will be a hierarchical list of bookmarks, grouped into categories. The categories can be expanded/contracted to show or hide the bookmarks for that category. Right now I'm just working on the UI and using jquery for the first time (and loving it).
The methodology I'm using is sorta like accordion but more than one section can be opened at the same time, and there can be multiple levels deep (accordion only supports one level). For each category, there's a div with an image of a folder in it that will show or hide the next element in the DOM, which would be the collection of bookmarks (usually a <ul>). eg:
<div class="categoryLine" id="d4">
<img class="folder"....>
Fourth Menu Item
</div>
<ul id="u4">
<li id="l41">
I select the element to close using $(this).parentsUntil('categoryLine').next().toggle(transitionSpeed); where the div around the image the user clicks on has a class of categoryLine, and the thing to show/hide is the element following that div.
The problem is in the most complex (deepest hierarchy) part, some things are being hidden that shouldn't be, and reappearing for unknown reasons.
You can see a "working" example here. I've given the relevant tags IDs and put in a debugging alert to display the ID of the element clicked on and the elements to be opened and closed (view source to see this).
Click on the folder for "Fourth Menu Item" to unhide that category. You should see sub 1, sub 2, and sub 3 appear.
Click on the folder for "Fourth Menu Item sub 1". You should see sub 1 expand, but sub 2 completely disappears, including the category line. This is the mystery I'm trying to solve. Clicking on sub 1 correctly says "Toggling 'u411' from category 'd41'" but when the <ul> u411 disappears, so does all of sub 2 disappears. Likewise, if I click on the folder to expand sub2, sub3 disappears.
I am open to implementing this in a completely different way (again, this is my first jquery experiment). I would also be willing to look at solutions where only one category could be open at a time, as long as it still supported a hierarchy instead of one deep like accordion.
Thanks in advance.

jQuery describes parentsUntil() as:
Description: Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector.
The important part to note there is that you're not selecting .categoryLine. It seems as though you want to be including it though. Should work if you use closest() instead.
$(this).closest('.categoryLine').next().toggle(transitionSpeed);
As a side note for future reference. ('categoryLine') is not a selector. Typically, you need to include the ., # or element type, ie div. There are more advanced methods though. You may want to read up on jQuery selectors.
