This new version contains updated API for `showLoadingIndicator` 2.0.1|May 1, 2017|Updated to SPFx GA 2.0.0|November 22, 2016|Added new sample web part (Dropdown with remote data (without custom controls)) 1.0.0|October 17, 2016|Initial release ## Minimal Path to Awesome - clone this repo - `$ npm i` - `$ gulp serve nobrowser` ### Asynchronous drop-down By default the control uses mock data. If you want to test the control with SharePoint, change the commented sections in the `DropdownWithRemoteDataWebPart.ts` file inside the `loadLists` and `loadItems` functions and deploy the sample web part to your SharePoint developer tenant. ### Drop-down with external data without using a custom control By default the web part uses mock data. If you want to test it with SharePoint, change the commented sections in the `DropdownWithRemoteDataWithoutCustomControlsWebPart.ts` file inside the `loadLists` and `loadItems` methods and deploy the sample web part to your SharePoint tenant. ## Features Sample web parts in this solution illustrate the following concepts on top of the SharePoint Framework: - using React for building custom property pane controls for use with SharePoint Framework client-side web parts - building custom property pane controls using TypeScript - updating web part properties from custom property pane controls - linking multiple custom property pane controls together - loading data for use in custom property pane controls asynchronously without blocking the web part - forcing React components to repaint using an external trigger - displaying a custom loading indicator - reacting to web part property changes - updating properties of web part property pane controls - refreshing the web part property pane from the web part ## Help We do not support samples, but this community is always willing to help, and we want to improve these samples.
