Dash dropdown to select dataframe


I am new to dash and I was able to create simple dashboards with one dataframe. Right now, I have around 120 excel files, with same or similar column names (t1, t2 …) and I would like to create a dashboard, where will be dropdown menu to select from which datagrame should the data be taken.

Is something like that possible ? Can you provide some sample code, how to do it ?
Thank you


It is possible to do it. Even if the files are “static”, I would still recommend you to import the using a callback and not loading all of them in memory.

What exactly do you want to do with the data after it is imported?
