Options to upload the data set after deployment

Hello Everyone,

I developed a dash app and now I am working on my local server. I am using pandas to read data from my local PC but now I want to deploy this app in the remote server where all people can access.

The problem which I am not understanding is

  1. How to read the data after deployment?

  2. I have gone through the UPLOAD component. Once the data is uploaded how to use data columns in dropdowns?
    for example, I need to select only some features from the data set so from which component I have to select the features. From which variable I can get dropdown options? I am completely confused about it.

If anyone has solved this type of problem please help me.
