## Usage
|

|
|
#### Mock Data configuration by using defaultOptions configuration
|

|
|
Configuration:
|
|
```js
|
|
PropertyPaneTaxonomyPicker("Language", {
|
|
key: "Language_Field",
|
|
name: "Language",
|
|
displayName: "Language",
|
|
multi: true,
|
|
defaultOptions: [
|
|
{ label: "English", value: "f50249b6-310d-43b6-aaa6-f0cb46d851bf" },
|
|
{ label: "Spanish", value: "237ca323-1ed8-4199-a49b-a9f7ce4256bf" },
|
|
{ label: "German", value: "44024c7e-f738-4755-90e1-15866327c806" },
|
|
{ label: "Italian", value: "65f67491-bdca-491a-84fa-f6fd913f40fa" },
|
|
],
|
|
onPickerChange: this._updateTaxonomyPicker
|
|
})
|
|
```
|
|
#### Real Data configuration by using termSetGuid configuration
|
|
Access from https://your-domain.sharepoint.com/_layouts/15/workbench.aspx
|
|
Configuration:
|
|
```js
|
|
PropertyPaneTaxonomyPicker("Language", {
|
|
key: "Language_Field",
|
|
name: "Language",
|
|
displayName: "Language",
|
|
multi: true,
|
|
termSetGuid: "<your-term-set-id>",
|
|
termSetName: "Language",
|
|
termSetCountMaxSwapToAsync: 100,
|
|
onPickerChange: this._updateTaxonomyPicker
|
|
})
|
|
```
|
|
|
|
## Features
|
|
- Use [React](https://facebook.github.io/react) for using [react-taxonomypicker](https://github.com/jquintozamora/react-taxonomypicker) control inside a custom property pane (it can be used in the web part itself too).
|
|
- Use [TypeScript](https://www.typescriptlang.org) to create the custom property pane control containing the taxonomy picker control.
|
|
- **Reacting to web part property changes**
|
|
- Loading data for use in **custom property pane controls asynchronously** without blocking the web part
|
|
- **Retrieve Terms** from a Term Set by Term Set GUID.
|
|
- **Sync / Async modes**
|
|
- Sync mode is used for medium / small Term Sets and loads **asynchronously** all Terms and store them in React State and SessionStorage cache.
|
|
- Async mode is used for large Term Sets and it **doesn't load any data initially**, but it loads the Terms upon user input in batches of 10 items.
|
|
- Sync / Async mode configurable via **termSetCountMaxSwapToAsync** property
|
|
- The control will fetch the number of terms and decide which mode to use depends on termSetCountMaxSwapToAsync value.
|
|
- It Uses and depends on **SP.Taxonomy.js** (the web part uses a wrapper to load all the SP.*.js dependencies)
|
|
- Use **Promise** (polyfill it if needed IE)
|
|
- **onPickerChange** event handler exposed
|
|
- [react-select](https://github.com/JedWatson/react-select) properties exposed (extends them)
|
|
- defaultOptions array exposed to enable input **mock data** when no termSetGuid configured
|
|
- More configuration options: [react-taxonomypicker](https://www.npmjs.com/package/react-taxonomypicker)
|
|
|
|

|
|
- SharePoint Web Part using **Script Editor** or **Content Editor Web Part**
