FAQ accordion widget html for Instapage

I’m looking for a customizable FAQ accordion style widget that supports categories (I have a lot of FAQs) and is compatible with Instapage. Most of the FAQ widgets I am seeing on Envato are made for WordPress. To be compatible with Instapage, the widget must use HTML.

Here is the help page for your reference: https://help.instapage.com/hc/en-us/articles/205221768-Embedding-custom-HTML-or-widgets-into-an-Instapage-landing-page

I found this widget but it’s too basic (I need something that can support categories): https://widgetic.com/widget/faq-accordion

Do you know where I can find such widgets?
