[4pt] -Display Comments pop up with selected item's details - Student B

Create a comments popup only with the top section (displaying details of the selected item)

When the popup loads, the webapp retrieves data from the selected API and shows details about the selected item.

Add event to button prepared by your teammate that will open your popup. You need to communicate with your team member to make sure that you do not block each other (most likely the easiest solution is to merge the list of items feature to the dev branch before you try to add that event).

首先定位 issue 中描述的已准备好的按钮、项目列表功能以及所选项目的数据流。添加顶部区域的评论弹窗，从选定的 API 项目加载详细信息，并连接按钮事件；选择项目时能打开包含其详细信息的弹窗即表示完成。

由索引模型根据 Issue 内容生成。
