+## FAQ
+
+### Part of the api in v2 are not available in v3?
+
+AutoComplete is an Input component that supports auto complete tips. As such, it should not support props like `labelInValue` that affect value display. In v2, the AutoComplete implementation can not handle the case where the `value` and `label` are identical. v3 not longer support `label` as the value input.
+
+Besides, to unify the API, `dataSource` is replaced with `options`. You can migrate with the following change:
+
+#### v2
+
+```ts
+dataSource = ['light', 'bamboo'];
+// or
+dataSource = [
+  { value: 'light', text: 'Light' },
+  { value: 'bamboo', text: 'Bamboo' },
+];
+```
+
+#### v3
+
+```ts
+options = [
+  { value: 'light', label: 'Light' },
+  { value: 'bamboo', label: 'Bamboo' },
+];
+```

+## FAQ
+
+### v2 的部分属性为何在 v3 中没有了？
+
+AutoComplete 组件是一个支持自动提示的 Input 组件，因而其不具有 `labelInValue` 等影响 value 展示的属性。在 v2 版本，AutoComplete 实现存在输入值如果遇到 `value` 与 `label` 相同时无法映射的问题。 v3 中不再支持 `label` 为值的输入形态。
+
+此外为了统一 API，`dataSource` 改为 `options` 你可以如下转换：
+
+#### v2
+
+```ts
+dataSource = ['light', 'bamboo'];
+// or
+dataSource = [
+  { value: 'light', text: 'Light' },
+  { value: 'bamboo', text: 'Bamboo' },
+];
+```
+
+#### v3
+
+```ts
+options = [
+  { value: 'light', label: 'Light' },
+  { value: 'bamboo', label: 'Bamboo' },
+];
+```
