I built a website with a date picker function to filter table from database based date picked. In the web page there is box that whenever clicked will have a drop down calendar and user can pick a date to fill the box. But it does not working(no drop down when the box clicked). I test the similar page on my localhost and it works without problem. Test it on my second webhosting and it also work. Here is the script source I used:
http://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js
http://code.jquery.com/ui/1.10.3/jquery-ui.js
http://code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css
And your website is?
