第二个手风琴不会显示

Question

我有一个手风琴，我想在它旁边添加另一个，但由于某种原因它无法显示，我不明白为什么。我将代码放在tryit editor v3.6 online中，显示效果很好。我使用的是每个脚本的最新版本，除了 bootstrap 5 beta，我使用的是 4.5。

PS：在我说更多之前，Stackoverflow 不会让我发布，但我没有更多，所以我会添加一些 lorem ipsum：Lorem ipsum dolor sat amet，consectetur adipiscing elit。 Cras auctor augue mauris, ac vehicula lorem dignissim sat amet。 Donec consectetur risus a placerat lobortis。 Mauris posuere sapien ac arcu facilisis，非 pellentesque diam semper。 Etiam luctus vehicula dictum。 sed pellentesque augue eros, sed venenatis ex scelerisque a. Sed luctus tristique。

我希望这会有所帮助。

我认为问题在于您在 <div id="accordion2"> 的 ID。 您可以在手风琴“问题四”之前找到它。 我尝试了您的代码并将 id 从“accordion2”更改为“accordion”。
