Cascade drop down in Office 365 (SP 2013)

Is there an easy way to implement Cascading Drop down in MS Office 365 SharePoint 2013 team site in a document library?

I have done it in SP 2007, 2010 using JQuery but same approach does not work in SP 2013. I noticed that SP 2013 does not generate regular standard HTML tags in browser output. It used to be <Select> until SP 2010 for a drop down. It is now changed. Any idea on how to deal with cascading drop down OR how to attach JQuery to SP 2013 EditForms.aspx page with a Drop down type field.
