Readme

Quick Start

Install Package

dotnet add package jcdcdev.Umbraco.ExtendedDropdownEditor

Create Data Type

  • Go to the Settings section in the Umbraco backoffice
  • Create a new Data Type using the Extended Dropdown editor.
  • Select your data source (File Picker, File Path Override, or URL).
  • Save the data type.

Now you are ready to use the data type in your content types!

Extending

File Picker

Select any file in the wwwroot or App_Plugins directory

Examples

  • wwwroot/data.json
  • App_Plugins/data.json

[!WARNING] Please note that any files in these directories are publicly accessible via URL!

File Path Override

Specify a custom path to a file (relative to the root of the web project)

Examples

  • /umbraco/Data/MyDataSource.json
  • /usync/v15/DataSources/countries.json

[!NOTE] This allows you to configure a path that is not publicly accessible via URL

URL

Specify a URL that returns a JSON response

  • Supports GET requests with optional query string parameters
  • Supports local and external URLs
  • Does not support authentication (yet 👀)
Examples
  • /myapi/mydata?format=json
  • https://array-3yn8gu6xn98t.runkit.sh/

Data Format

Currently, the data source must return an array of strings.

[
  "Item 1",
  "Item 2",
  "Item 3"
]

[!NOTE] In the future I plan to add JSONPath support to allow for more complex data structures 🤓
