如何使用带有无线电前置的输入来选择一些此类输入之一

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>

然后得到这个输入：

我想做一个组件来根据此输入选择 2 个或多个值中的一个。 例如，

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

但是文档说：

注意：您必须使用原生单选和复选框输入，如 并包含输入中不需要的附加标记 组。

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。

如果有人感兴趣，解决方案是：
子组件

<template>
  <b-container fluid>
    <b-form-group
      :label="formLabel"
      class="mb-1"
      label-class="text-center">
      <b-row>
        <b-col class="pl-2 pr-1">
          <b-input-group
            size="sm"
            сlass="mb-1">
            <b-input-group-prepend is-text>
              <input
                v-model="selectedValue"
                :value="oldValue"
