如何在litelement中将选中属性设置为单选

import { LitElement, html, css } from 'lit-element';

class MyElement extends LitElement {
  static properties = {
    selectedOption: { type: String }
  };

  constructor() {
    super();
    this.selectedOption = '';
  }

  static styles = css`
    :host {
      display: block;
    }
  `;

  render() {
    return html`
      <label>
        <input type="radio" name="options" value="option1" @change="${this.handleOptionChange}">
        Option 1
      </label>
      <label>
        <input type="radio" name="options" value="option2" @change="${this.handleOptionChange}">
        Option 2
      </label>
      <label>
        <input type="radio" name="options" value="option3" @change="${this.handleOptionChange}">
        Option 3
      </label>
    `;
  }

  handleOptionChange(event) {
    this.selectedOption = event.target.value;
  }
}

customElements.define('my-element', MyElement);
