Description

dash                     2.16.1
dash-core-components     2.0.0
dash-html-components     2.0.0
dash-table               5.0.0

The sample code:

import dash
from dash import html, dcc

app = dash.Dash()

app.layout = html.Div(
    [
        dcc.Checklist(
            [
                {
                    "label": dcc.Input(
                        id=f"input-{value}", persistence=True, style={"width": 100}
                    ),
                    "value": value,
                }
                for value in list("abc")
            ],
            labelStyle={"display": "flex", "align-items": "center"},
        )
    ],
    style={"padding": 50},
)

if __name__ == "__main__":
    app.run(debug=True)

Research direction

Start by running the provided Python sample with the listed Dash, dash-core-components, dash-html-components, and dash-table versions. Reproduce the checklist behavior and inspect whether the persisted dcc.Input values survive the component update shown in the demo. Done means persistence works for inputs used as checklist labels, with a regression test covering the sample case.
