Hi there!

I'm posting my question here, I'm not sure if it's the right place for this.

I'm trying to integrate a data_editor with a tabs widget.

Here is my code:

import marimo as mo
import pandas as pd

df = pd.DataFrame({"A": [1, 2, 3], "B": ["a", "b", "c"]})

editor = mo.ui.data_editor(data=df, label="Edit Data")

dict_tabs = {
    "tab1": editor,
    "tab2": "test"
}

tabs = mo.ui.tabs(
    tabs=dict_tabs,
)

tabs

But when I'm editing the data_editor and then switch the tab, the values I edited just disappear.

Is it an expected behavior?
How should I do if I want to integrate an editable data_editor within a tab?

Thanks for helping!
