# 建立 HTML 面板外掛程式
顯示 HTML 頁面的面板式外掛程式有一個結構如下的 *manifest.json* 檔案：
```
{
"PluginName": "Hello Block!",
"PluginType": "Panel",
"PluginDescription": "Creates a panel with an HTML form that allows dimensional input for a 3D block which will get generated at the world origin.",
"Scripts": [
"PLUGINLOCATION/block.js"
],
"Panel": "PLUGINLOCATION/hello_block.html",
"PanelIcon": "PLUGINLOCATION/hello_block.png"
}
```
除了[標準的 JSON 性質](/zh-tw/plugins/how-to-develop-plugins/advanced-development/general-plugin-setup-in-the-manifest.md)，面板式外掛程式還包括以下特殊的 JSON 性質：
* 「Panel」告訴 FormIt 此外掛程式是一個面板，並連結至應載入面板中的 HTML 檔案位置。
* HTML 檔案的標頭中需要指向相應 JavaScript 檔案的連結，以及用於設定樣式的 CSS 檔案。
* HTML 檔案將在 FormIt 面板中呈現，如同在瀏覽器中一樣。
* 您可以在 [FormIt3D 組織](https://github.com/FormIt3D/)中查看 Rich HTML 介面的範例。
* 「PanelIcon」定義此外掛程式顯示在應用程式右側頁籤中的圖示。如果未定義，FormIt 會使用外掛程式名稱的首字母建立自動圖示。
設定 HTML、CSS 和 JavaScript 檔案後，您可以透過[載入或安裝](https://windows.help.formit.autodesk.com/zh-tw/plugins/how-to-develop-plugins/additional-development-options/pages/38SePUTZAA8xUmVUmUsJ#load-vs.-install)來開始測試 HTML 面板外掛程式。
