How to show a different div after selection of a country in a dropdown menu in WordPress? [closed]

Working on WordPress & Elementor and Neve theme.
I would like to display 2 columns in a block.
First column would have a dropdown menu with the list of all the countries.
The second column would show a different div with different informations, depending on the country selected in the dropdown menu.
The div would countain a different picture/text and a button to send a tweet.
I’ve searched for hours but I think I can’t make a proper research because of all of the informations I’m trying to precise through my keywords
