概述

Kendo UI For Angular Chip允許用戶輸入信息、做出選擇、過濾內(nèi)容或者觸發(fā)動作。

Chip以緊湊的形式表示一個復(fù)雜的信息片段，例如一個實體可以是一個人、一個地方或一個事物，可以單擊或刪除組件，并支持各種樣式選項。Chip通常用于電子郵件模板，其中每個Chip是一個人。

下面的示例演示了實際的Chip。

關(guān)鍵特性

• 內(nèi)容—您可以通過傳遞字符串或使用自定義配置選項來指定芯片的內(nèi)容。
• 用于不同用例的Chip集—根據(jù)需求，您可以實現(xiàn)不同的Chip集，以緊湊的形式顯示復(fù)雜的信息，例如用于集合的過濾器、具有多個選擇選項的多個Chip、可以由用戶動態(tài)添加或刪除的文本條目等等。
• 自定義—你可以添加一個選擇或刪除自定義圖標(biāo)的Chip，以及顯示在它的頭像。
• 外觀—Chip提供即用型，預(yù)定義的造型選項集。
• 全球化—所有Kendo UI for Angular Buttons都提供全球化選項。
