Hello @LukasMasuch! Is there a timeline for this feature by any chance?

[LukasMasuch]

@juliahansmeyer No timeline yet :( We haven't yet planned internally on getting this in, but maybe within the next 2-3 months if I find some time. What's your use case for this feature?

[juliahansmeyer]

@LukasMasuch I am working on a dashboard for a client to collect data in a more structured manner. If we're able to include multiselect columns in the data_editor, we could limit the input options and collect data for a machine learning use case to do predictive maintenance on machine data with customer input.
Currently we are using a workaround, but having a multiselect column like the app category column in your demo is essential for usability and our current version is too complicated to use.
Is there any chance this feature could be prioritised?

[juliahansmeyer]

When you find the time and have any estimate on when the feature will be included, I'd be super happy to be updated! Thanks a lot already @LukasMasuch!! :)

[LukasMasuch]

@juliahansmeyer I will post an update to this PR thread as soon as we decide to pick this up :)
