How do I change the placeholder when multiselect is no option?

Using Streamlit

In my use case, I want users to be able to type freely into st.text_input(), and when they add a comma (,), it should behave like a multi-select input. I checked the documentation for st.text_input(), but couldn’t find a way to implement this behavior.

As an alternative, I tried using st.multiselect() with accept_new_items=True, and I’m passing options=None so users can enter anything without choosing any option. However, it seems that when options is None, I can’t set a custom placeholder for the input (the placeholder still default even though I change it trhough multiselect’s parameter).

Is there a way to make the placeholder editable or customizable in this case?

title_search = st.multiselect(
    label="Title Search",
    options = None,
    placeholder='Keywords in Title',
    label_visibility='collapsed',
    accept_new_options=True,
    key='title_filter'
)
