I got curious if there was an easy way to find websites like that, and it seems like websites that allow you to search in the html of pages work for that. Here's an example, though you get limited results here unless you get a subscription.
You could also check out the websites of the official mendix partners, most of them have some use cases on their website where you can see some of the results.
Kindly have look into mentioned link
Hope it will be helpful for you.
