You moved your custom code our of the page - into the project.
And because of that… I cannot see your custom code…
other than the 2 div’s you created in the page/custom code section.
Just clone the project I provided… that way you can go through step by step.
In summary
in your header section… place the jqueryui css.
in the footer section… place the jqueryui function and the http call to grab the jqueryui library.
As @samliew said… don’t add the jquery code. Webflow already includes the jquery link for you.
Im leaving the office now and heading home.
I have more work to do at home… so I’ll be up for awhile.
The demo should be pretty self-explanatory though.
Take a look at it.
