So far I've been using jquery ui's draggables and droppables, but I've also heard of extjs and I'm sure there are more. I'm looking to develop a (hopefully) professional plugin. What would be the best library to use and or is anyone aware of any limitations to jquery ui's functions for this?
I'm going to need to go 1-3 layers deep at least of dropping things inside each other, if not more.

There are various options available to you even including the possibility of writing your own drag and drop functionality if you really wanted.
jQuery UI isn't a bad choice and there will be plenty of support going down that route. jQuery UI sortables sounds to fit the behaviour you desire. I've used this for nested drag and drop in the past.
dragula is a nice vanilla js alternative for drag and drop behaviour supporting IE7+ that could also be a good choice.
Hope that helps!

Depends on the browsers you need to support. HTML5 has native drag & drop support, so if you only have to support IE9 and above, you can just use the attribute draggable=true and handle the drag events; see http://www.w3schools.com/html/html5_draganddrop.asp for examples. If you need to support IE8, however, jquery ui is the best (read: easiest) I've used.

We have a web application designed for pc browsing. For this application we used infraguistics grid control to present information and some of them are hierarchical. We can group by columns, sort them etc.
We want to convert this application to Ipad compatible web application. We are thinking about using jquery mobile, but it is still early stage. There is no grid like control in jquery mobile, there are controls like list and Collapsible but nothing like grids with flexibility like sorting, grouping etc.
Is there is any other options or suggestions.
We are not really focused on Jquery mobile it could be anything but should be javascript based.
Thanks,
You may use JSLightGrid plugin. It's responsive, supported by mobile browsers, very light weight and very good in performance, in short good for mibile applications. https://github.com/chanakyachatterjee/JSLightGrid
But you need to write your custom code grouping unless they include it in next version.
It's pure javascript.
Mobile web frameworks are not as mature as desktop frameworks. The features you're describing are difficult to achieve within the constraints of a mobile environment. I don't know of a mobile framework that will do what you need.
Your options are:
Build this yourself using something like jQuery Mobile as a base (I would use Sencha Touch).
Pay someone to do #1.
Alter your iPad design so that it doesn't require this feature.
(Sorry I don't have better news.)

I know these types of "questions" are discouraged but since I have quite specific needs I believe this question does have a definitive answer.
I need an image carousel that meets the following requirements:
I can make my own transitions (basically I want to apply a class and have a CSS transition)
Mobile support with swipe
My own markup if possible
Manual switching as well as automatic switching
Is there any library like this out there?
I've tried Flexslider but it doesn't allow me to have my own transitions.
Maybe I'm better off just using Swipe JS and writing my own transitions, though there are many edge cases to be aware of so I'd rather not do this myself.
jQuery Cycle is a very good plug in that mostly does what you want.
http://jquery.malsup.com/cycle/
You can use any of the default transitions or create your own named ones in the options.
http://jquery.malsup.com/cycle/adv2.html
I ended up using a custom built version for desktop and SwipeJS for touch devices.

I've been searching for a long time now for a fairly simple JavaScript based tooltip solution. It needs to be:
Open-Source and freely re-distributable, and allows my application to include it which would be distributable via free or commercial license.
'Sticky' i.e when opened it stays visible until the user clicks a little close button on it or ESC button is pressed.
Style-able via CSS (preferably) or JavaScript.
Compatible with IE6 or IE7 onwards, as well as modern browsers ;)
I did manage to find http://www.nickstakenburg.com/projects/prototip2/ (see the buttons example on that page) which meets all the requirements - except that I wouldn't be able to distribute what I'm creating for free which makes it a no-go :(
It only needs to able to handle basic HTML (div, p, span, img, etc) within the tooltip.
Thanks,
Alex
Use qTip a jQuery based opensource tooltip plugin, you can control the events when to show the tip. for example show: { when: { event: 'click' } } this will show the tooltip on click on the target element. Hope this helps
If you're looking for a tooltip that also works without a library (like jQuery) you can use Opentip which uses adapters for all major frameworks, and provides a native adapter that doesn't need a framework.
It's open source and MIT licensed.

Looking to implement one on a website, just curious what everyone else has used and what kind of experiences they've had
EDIT I'm also not a huge fan, but the client is insistant and for this case they can click on the "hoverable" part and then get to the same pages in the dropdown from there so basically this will just be a way to get to pages with one less click
I really like the Suckerfish dropdown menu from A List Apart. It's really easy to implement (I've done it myself, and I'm not much of a Web programmer), and even works in IE.
I use the YUI Menu. It's quite flexible, offers many methods of declaring what's in the list, and is easy to skin.
Superfish is a jQuery enhancement of Suckerfish and supports several levels of dropdown and various layout options.
It degrades nicely:
With Javascript and CSS, the dropdowns fade in nicely and the menu has other enhancements.
With CSS only, the dropdowns still work (IE6 is supported).
With neither, the menu degrades to an unordered, nested list.
I am using this now and like it.
I use the on on Steve Gibson's site grc.com. It is purely CSS -- uses no Javascript. It's not all that intuitive, and there are parts that are IE-specific, but it works well.
It's worth checking out superfish which expands slightly on suckerfish
I recommend mygosuMenu.
from the page:
- horizontal or vertical menu
- can be positioned statically or absolutely
- delay for showing/hiding menu (can be turned off by setting to 0)
- position of submenus can be changed, so they can for example overflow parent elements
- on the same page there can be many menus created
- seperated into 3 layers: behaviour(javascript), structure(html), presentation(css)
- search engine friendly
- free for any use (BSD license)
I don't like them, tend to avoid them as much as possible.

Does anyone have a good recommendation for a drop shadow jQuery plugin?
I've been working on a project that had every element on the page with a subtle drop shadow, we started using RUZEE to do the shadows but there was a severe performance hit when you had more then 4 or 5 shadows being calculated on the page.
I went to writing my own plugin, I call it simple shadow and it only uses jQuery to inject images in floating div's around the div you want a drop shadow. Nothing elegant but for the purpose of completing that site it worked without performance hits.
Now my plugin isn't anything special but I am still in search for a good light weight shadow plugin.
CSS 3 will support drop shadow. Firefox and Safari are already supporting the feature.
You might want to use that instead of the jQuery functionality, since it will run in browsers who have turned off javascript.
Take a look at http://www.css3.info/preview/box-shadow/ for a demo of the shadow.
The original site hosting the jQuery Dropshadow plugin has apparently gone down.
For anyone looking for it, I'm currently hosting it on my Dropbox account.
jQuery UI also provides drop shadow functionality.
The JQuery UI no longer supports shadow functionality.
try the FontEffect jQuery Plugin, sorry I can't post the link, but you can find it easily on google or jQuery plugin site.
