New & Improved Cascading Dropdowns for SharePoint Classic Forms
Almost three years ago I posted a script on how to create cascading drop downs for SharePoint 2013 and SharePoint Online using REST.
Cascading Drop Down Lists in SharePoint / Office 365 using REST
Since then I’ve had a lot of comments asking for additional functionality to that script. So, I decided it was time to update the script and make it a little more modular. If you are a user of the previous script, the biggest change you will see is how you execute the cascade function. Now, instead of passing in an object to the cascade functionality, you pass in an array of objects. This allows you to set up multilevel cascading.The updated script can be found on GitHub at https://github.com/mrackley/HillbillyCascade
As always, take a look at the video at the end of the blog post for step by step instructions and to see the script in action.
