Definitely! Don't worry about a limit, you can use as many as you want as long as they’re adding value. Here are a couple examples:
- Using plugins to manage behaviors outside the scope of Bootstrap’s core (datepicker, calendar, etc) is great, but discourage replacing existing functionality (tooltips, modals, carousel).
- Using plugins to provide different charting possibilities is great (Morris, Charts.js, etc), but we discourage using major charting library to replicate the exact same charts in excess.
Just be sure the license of the library you're developing with supports your use case and outline any restrictions on the theme's page so buyers know what they're getting.
