Improve the user experience on my website by implementing a search feature for US states and Canadian territories. When visitors type in their selection, I want them to be able to click on an icon that will reveal relevant information about that choice.

This example, originally from CodeNepal but customized by me, demonstrates what I'm looking for. Instead of redirecting users to a Google search page, I want a specific box to expand below the searchbox when they make a selection. I understand that the "weblink" line needs to be modified to achieve this functionality, but I'm unsure of how to adjust it to show/hide a div element or something similar.

Note: Rather than linking each selection to a database entry, I plan to manually code each one into separate div elements with anchors.

 <div class="wrapper">
   <div class="search-input">
     <a href="" target="_blank" hidden></a>
     <input type="text" placeholder="Type to search..">
     <div class="autocom-box"gt;
       <!-- data list inserted dynamically using JavaScript -->
     </div>
     <div class="icon"><i class="fas fa-search"></i></div>
   </div>
 </div>
