Have you ever wanted a drag and drop library that just works? That doesn't just depend on bloated frameworks, that has great support? That actually understands where to place the elements when they are dropped? That doesn't need you to do a zillion things to get it to work? Well, so did I! If you're not using either package manager, you can use dragula by downloading the files in the dist folder. We strongly suggest using npmthough.

There's a caveat to dragula. There's a few CSS styles you need to incorporate in order for dragula to work as expected. If you're using Stylus, you can include the styles using the directive below.

By default, dragula will allow the user to drag an element in any of the containers and drop it in any other container in the list. If the element is dropped anywhere that's not one of the containersthe event will be gracefully cancelled according to the revertOnSpill and removeOnSpill options.

The example below allows the user to drag elements from left into rightand from right into left. You can also provide an options object. Here's an overview of the default values. And you could also not set any arguments, which defaults to a drake without containers and with the default options. Setting this option is effectively the same as passing the containers in the first argument to dragula containers, options.

Besides the containers that you pass to dragulaor the containers you dynamically push or unshift from drake. The example below dynamically treats all DOM elements with a CSS class of dragula-container as dragula containers for this drake.

You can define a moves method which will be invoked with el, source, handle, sibling whenever an element is clicked. If this method returns falsea drag event won't begin, and the event won't be prevented either.

The handle element will be the original click target, which comes in handy to test if that element is an expected "drag handle". You can set accepts to a method with the following signature: el, target, source, sibling. It'll be called to make sure that an element elthat came from container sourcecan be dropped on container target before a sibling element. The sibling can be nullwhich would mean that the element would be placed as the last element in the container.

Note that if options. Also note that the position where a drag starts is always going to be a valid place where to drop the elementeven if accepts returned false for all cases.

If copy is set to true or a method that returns trueitems will be copied rather than moved. This implies the following differences:.

If a method is passed, it'll be called whenever an element starts being dragged in order to decide whether it should follow copy behavior or not. Consider the following example. If copy is set to true or a method that returns true and copySortSource is true as well, users will be able to sort elements in copy -source containers.

By default, spilling an element outside of any containers will move the element back to the drop position previewed by the feedback shadow.

Setting revertOnSpill to true will ensure elements dropped outside of any approved containers are moved back to the source element where the drag event began, rather than stay at the drop position previewed by the feedback shadow.I looked around and found a great library called Dragula which gives AngularJS apps great features.

This Tutorial was updated for Ionic 3. Therefore today I will show you how to easily add drag and drop to your Ionic app by including and using ngDragula. Learning Ionic can become overwhelming, I know that feeling. Is learning from tutorials and videos sometimes not enough for you? Then I got something for you. If you want to learn Ionic with step-by-step video courseshands-on training projects and a helpful community who has your back, then take a look at the Ionic Academy.

Join the Ionic Academy. As always we start with a blank Ionic app. We also already install the ng2-dragula library wich is the version of Dragula for Angular 2. So go ahead and run:. You can also specify all kinds of attributes how the drag or drop feature should behave in special cases. For us, we simply want to have 2 Ionic lists side by side and drag and drop items between those 2 lists.

To use the library we need to import it inside our class and add the directive and provider of ngDragula to our component. Inside our class we have 2 arrays for our 2 lists. For an example we also subscribe to the drop event of the DragulaService and create a little alert.

This means, whenever we drop something it should appear in the new place and also a popup should come up. As you can see, we specify the name "my-bag" to let Dragula know those 2 lists have a connection, and for each list we specify either q1 or q2the arrays from our previously created class. Now this should already work, but to get the cool effects you might have seen on the Demo page we need to add some styling, which we can directly take from Dragula.

The best way to do so is writing your own copy config for NPM packages, which I have described here.


These animations and stylings will add the effect of items floating above the rest while dragging and getting smooth into their new position. What are your experiences with other frameworks for animation or cool features? Let me know your experiences! Share Start a new Ionic 2 project and install Dragula. MyApp.

How to Build Ionic 2 Drag and Drop using Dragula

There are plenty of events along the lifetime of a drag event. Check out all of them in the docs!

dragula angular

As soon as you start dragging an element, a drag event is fired. Whenever an element is cloned because copy: truea cloned event fires. The shadow event fires whenever the placeholder showing where an element would be dropped is moved to a different container or position. A drop event is fired whenever an element is dropped anywhere other than its origin where it was initially dragged from. If the element gets removed from the DOM as a result of dropping outside of any containers, a remove event gets fired.

A cancel event is fired when an element would be dropped onto an invalid target, but retains its original placement instead. The over event fires when you drag something over a container, and out fires when you drag it away from the container. Lastly, a dragend event is fired whenever a drag operation ends, regardless of whether it ends in a cancellation, removal, or drop.

Need to be able to quickly delete stuff when it spills out of the chosen containers? Note how you can easily sort the items in any containers by just dragging and dropping.There are many ways to add some drag and drop functions to your Ionic app, but using the Dragula package has been my favorite so far and something you enjoyed with Ionic 3 previously as well.

To get started with our app we create a blank new project and simply install the ng2-dragula package:. Finally we need some CSS so the drag animation looks nicely.

With Dragula you can move objects around between groups if they share the same Dragula name. In our case we will have four different arrays for the quadrants of our app that hold the information, and we want to drag and drop items between them.

Within our constructor we can now use the Dragula service to subscribe to various events. All of these Observables can return a lot of values, and you can pick the ones you need. In our case we mostly need the actual item which holds the information of the object inside our data array, but you can get information about almost anything at that point!

Simply check out the signature of those functions. We are also changing the color in two different ways; While dragging we directly set the color attribute of the HTML itemlater we use the color property. Just wanted to show both options in here as they do pretty much the same.

Finally we also have a function to add a new todo to a specific quadrant. We need some logic here to check which color should be added but basically it just adds the information to the appropriate array.

First of all we need the information for a new todo which is the area at the top of our view. This helps to prevent some crazy scrolling on a device while dragging elements between the lists! At the bottom we have the four quadrants, and we could have another array to iterate so it would be only one code block but I thought it would be a bit more clearly how the package works if we write things out.

So within each column we have a little header for that area followed by a list of the todo items of that quadrant. Also, you need to pass in the [ dragulaModel ] which is the connection to the array with information for each quadrant. If you set up these things correctly you have established a connection between the different lists and also a 2 way data binding between the Dragula list and the actual array containing the information.

Whether you are directly following this tutorial or use your own view, adding some styling is important because Dragula might not work as expected otherwise. Besides that I played around with some other styling properties but feel free to experiment a bit more on a real device! The result should look pretty much like the image below.

You can drag the items between the different lists, you can add new items and also drop them outside to remove them. The delete area is basically just a UI indication to drop it, actually you can drop them anywhere outside the lists to remove them! Drag and drop is a pretty cool functionality if you can integrate it in a useful way inside your Ionic app.

Import to your lazy loaded page.Last week, I had to build an application that required drag and drop functionality. This made me learn about couple of third party Angular 4 drag-and-drop APIs. I found ng2-dnd more extensible and feature rich so I used it in my application. We will use Addy Osmani Angular 4 todomvc application as the starting point.

This post does not cover basics of how to build Angular 4 applications. There are many good references on the web that can teach you building Angular 4 applications from scratch.

To do that you can run the git clone command shown below. Now, change directory to todomvc-angular Install the dependencies and then start the application. Next, we will install the main dependency of our application ng2-dnd. This library will add support for drag and drop functionality. Next, we will import DndModule and declare it in the app. In Angular every application has one application level module that bootstraps the application.

The convention is to use AppModule as the name of the module class and app. As shown in the code snippet above, we added declaration of DndModule in the imports section. As we want to use drag and drag capability provided by ng2-dnd so we declared that in the imports section. The forRoot is a convention for modules that expose a singleton service. Now that we have imported DndModule we can add drag-and-drop functionality to our application. Update app. Component calls todo-data. In the app.

In this post, we looked at how easy it is to add drag-and-drop capability to the application by using ng2-dnd library. Try it out. I figured it out, it was just a little confusing when I was reading through it. Anyway, thanks for the walkthrough example. Has anyone tried using ng2-dnd to drag an element from inside a Modal and drop it outside while closing the modal once the element drags past the modal container?

The item you drag will be cloned and the clone will stay in the original list. Try sorting the list on the left. It is not possible because it has it's sort option set to false. However, you can still drag from the list on the left to the list on the right. Try dragging the item with a red background. It cannot be done, because that item is filtered out using the filter option. Try modifying the inputs below to affect the swap thresholds.

You can see the swap zones of the squares colored in dark blue, while the "dead zones" that do not cause a swap are colored in light blue. It is also always recommended that either the invertSwap option is set to true, or the swapThreshold option is lower than the default value of 1 eg 0. The MultiDrag plugin allows for multiple items to be dragged at a time. You can click to "select" multiple items, and then drag them as one item. The Swap plugin changes the behaviour of Sortable to allow for items to be swapped with eachother rather than sorted.
