Hi, I have a Streamlit application where I can upload some pdf files and then select the files I want to work on from a select box and they will be displayed in the main panel. Now instead of displaying all the selected pdfs one after the other, I wonder if it’s possible to dynamically open every selected file in a new tab with the file name as its title. Of course, if I un-select the file, the tab should disappear.

Any suggestions ?
