如何使用带有无线电前缀的输入到 select 一些这样的输入之一

Question

来自 bootsrap-vue 的文档（基于 bootstrap 4）：

<b-input-group>
  <b-input-group-prepend is-text>
    <input type="radio" aria-label="Radio for following text input">
  </b-input-group-prepend>
  <b-form-input aria-label="Text input with radio button"></b-form-input>
</b-input-group>

并获取此输入：

我想做一个组件来根据这个输入选择 2 个或更多值之一。例如，

selectedValue: null,
compareOptions: [{text: "Value1", value: option1}, {text: "Value2", value: option2}]

但文档说：

Note: you must use native radio and checkbox inputs, as and include additional markup not required in input groups.

我应该如何使用文档中的代码来设置 v-model 和选项以使其按预期工作。

  <b-container fluid>
    <b-form-group
      :label="formLabel"
