Build a Custom View for a Block
You can choose to customize your editing experience by implementing a custom view for each Block Type of a Block Editor.
By picking a custom view you overwrite the backoffice UI for the given block with your own. This enables you to define how a block should be presented. It can, however, also include interactive elements and be a full custom solution to how data is manipulated. In the Block List Editor the Inline Editing Mode must be disabled for custom backoffice views to appear.
Write your own HTML view
Currently you can only pick HTML files for a custom view. These views are powered by AngularJS and you can write any AngularJS logic.
Your HTML can be anything. If you use it as a representation of the content you would also want the full view to be clickable. This would then open the default editor for editing of your content.
The following example displays the property with the alias headline
together with the description
inside a button to edit your block.
If you would like to display properties of settings
, you can access these by using block.settingsData.myPropertyAlias
.
Make Block List Editor custom view draggable
A custom view of Block List Editor needs to have the 'blockelement__draggable-element' class presented to define which part of the Block that is draggable.
Example:
Adding custom implementation to your View
To achieve this you need to add a custom AngularJS controller to your custom view, using the ng-controller
attribute:
Create a folder inside the App_Plugins
folder called 'CustomBlockView'.
Create two files within the CustomBlockView file: package.manifest
and customBlock.controller.js
.
Add the following JSON to the package.manifest
file:
Umbraco will parse all package.manifest
files and load any resources they reference into the backoffice during startup.
The second file, customBlock.controller.js
, will be used to register the 'customBlockController' defined using the ng-controller
attribute in your custom view.
To register the controller, add the following lines of code:
Example: Displaying an image from a Media Picker
Your block may enable you to 'pick' an image for use as the background for a particular block. If you try to display this image directly in the view using block.data.image
, you will see the unique ID and not the image.
You will need to use the ID in our custom AngularJS controller in order to get the ImageUrl
to display in our backoffice Block Editor View.
With the setup of files above, you need to amend the customBlock.controller.js
file, by injecting the mediaResource
to retrieve the image from the ID:
Update the Custom View to use the imageUrl
property to display the image:
If you need to use a specific crop, you can inject the imageUrlGeneratorResource
resource, which has a getCropUrl(mediaPath, width, height, imageCropMode, animationProcessMode)
method:
