Below are the steps at high level that are to be followed with respect to the wiki article:

• Download the analysis named jqueryui-in-a-custom-javascript-10-0.zip that is available as an attachment in the community article at:https://community.spotfire.com/articles/spotfire/how-to-include-your-own-instances-of-jquery-and-jqueryui-in-text-areas/
• Open analysis jQueryUI-in-a-custom-javascript-10-0.dxp
• Right click > Edit HTML > and copy the script 'jQuery and jQueryUI' into your analysis.
• Now in the Edit HTML dialog of your analysis, add the above script and position it as the first script in the list of Scripts.
• Ensure that you have also added the Script parameter 'styleContainerId' with the value as 'style-container'
• Add the below div tag to the HTML Text Area 

  <div id="style-container">
    <!-- This element serves as a container for style elements added by the jQueryUI script. -->
  </div>

• And in all your JavaScript code you need to add the below line of code at the beginning.

  var $ = window.CustomJQuery;

Ensure that you have added the 'jQuery and jQueryUI' script at the top. And add the "var $ = window.CustomJQuery;" in all the necessary JS Scripts at the top so it refers to the libraries that are imported.
