Allow non consecutive dates when creating date picker with `mo.ui.date.from_series`

[fcusimano]

Description

When creating a date picker using mo.ui.date.from_series I would like to have the option to only show the dates present in my Series as selectable, even if non consecutive. For example in the image below, July 24 to 28 should be grayed out. My current use case is to select model training dates, where some days might be skipped.

Thank you!

Suggested solution

Perhaps a consecutive boolean parameter in from_series()

Alternatives

Currrently a possible workaround is to use a dropdown but it is less elegant especially with large amount of dates.

We can try to improve the formatting when inside a drodown, but you could use mo.ui.dropdown.from_series instead:

import datetime
import marimo as mo
import polars as pl

dates = pl.DataFrame(
    {
        "dates": [
            datetime.datetime(2025, 1, 1),
            datetime.datetime(2025, 2, 1),
            datetime.datetime(2025, 3, 1),
        ]
    }
)
mo.ui.dropdown.from_series(dates["dates"])
