 Okay, so I'm here to talk about a sortable model that we wrote for an Angular, and so I'm going to talk about the problem that we faced and why we have to come up with that model. So before, we have Lohit from Kendo, so he was talking about a lot of widgets, right? And he also mentioned that it has dependence on Jcode UI, and also it has some Angular stuff to do with that. So our project, yeah, basically I'm a full stack developer. I come from CollabNet, and we do development in Angular for our frontend needs. And so whenever a product is using Angular as frontend, and so we come up with, we face the problem so that we have to solve, we have to do some drag and drop, and we have to do some sorting, and so typically that is for ours. So typically that is for our storyboard. So I think you all know about the storyboard in today's, so the gelboard, right, so basically you have some stories and you have tasks. You have to just move from one status to another status, like from not starting to in progress, and in progress to then. So and all these stuffs you have to do, and so that is all about the storyboard. And for that we have to have a nice drag and drop UI widget, and since we use Angular, so we want to stick with Angular, and we don't want to introduce more frameworks or more plugins just to do this thing. And we looked at, so that Angular provides all these functionalities, but unfortunately we couldn't find any suitable library for us. So we have a library in Angular UI, it provides a sortable, but again it depends on jQuery UI, and the jQuery UI depends on the touch punch for touch to work. So we ran into kind of adding more dependency just to get this thing working. So what I did is just wrote a simple sortable plugin, which is purely done in JavaScript, and it exposes all the functionality through a simple Angular directive. And that is pretty much open. And so you can just, sorry, not this one, yeah, you can, yeah, you can just scroll down there, scroll down, scroll down, sorry, scroll down, scroll down. Yeah, so there are a few features like, I would like to, so you can do both vertical and horizontal sorting, and it provides a hook actually, so when you want to rank and you just change your order, so it provides a hook so that you can call your server API, and so when you do a move also, so you provide a hook there. And so there are a few more features we added, like, yeah, it's pretty simple, again the directive structure is pretty simple, you have a list and you have an item and you have your drag hook, so that's about it. And yeah, and you can pretty much play around with it and you have a lot of control so that you can control your dragging while you are doing your drag, sorry, so you can control your drag on specific targets by means of checking some simple checks here, yeah, yeah, probably, yeah, yeah, down, down, sorry, yeah, yeah, actually it has some fixes and like where you can handle your validation as well, so if you have any errors, so you can just do validation, simple validation, and so we have provided hooks for that, and probably just end up with a, finished with a simple demo, let me just, no, that one, the next one, next one, yeah, yeah, so yeah, so if you see this demo, so it has control over a specific column, so next one, next, you can drag this to everywhere, so it is just controlled to move to a specific columns, and that is validated at runtime, and yeah, this doesn't have any dependency on any of the libraries, and this is purely done using a pure JavaScript and it just exposes a simple Angular directive to use, and yeah, it supports all browsers and test devices and it's pretty much open and contributions, welcome, thank you.
