Hi,
There are two options to integrate js (+html) into a page:
- Using Generic JavaScriptComponent :: Jmix Documentation
- Implementing
BootstrapListenerwhich gives the access to the entire web page. The example of usingBootstrapListenercan be found on forum, e.g. here: Viewport problem - #2 by gorelov
Unfortunately, it’s hard to give any specific advice, since I don’t know which captcha lib you want to integrate.
Regards,
Gleb
