英文:
Could not use `streamlit` to annotate a dataset of multiple labels
问题
I am trying to build an annotation interface using streamlit.
In my dataset, each data point may have multiple labels (i.e. labels in the code below). However, I could only select one label using st.multiselect() rather than the expected "multiple select". Specifically, every time I click the one of the choices, the page will be updated and the next data point pops up.
I am not sure what went wrong after getting stuck in this for hours. Could anyone provide any pointers for me?

你可以使用 一个表单 来防止应用程序在与多选小部件交互后重新运行（相反，应用程序不会重新运行，直到你点击 "提交"）。
英文:
You can use a form to prevent the app from rerunning after interacting with the multiselect widget (instead, the app won't rerun until you hit "Submit").
