Joomla Custom Module Development - Backend administration Extra requirement

Question

I am currently in the process of developing a custom joomla module for one of my client’s requirement. As part of the administration panel of that module, I have created a radio button group, well in that group; I have two more radio buttons

My question for you leaders in the web arena is I need an option that "should display extra fields when I select one of the radio buttons"

For example: I have a radio button group named as 'No of fields'. In that group, I have two radio buttons named as 'Show', 'Hide'. I need an option which should display extra fields, when I select 'show' radio button

Is this equation possible? If yes, please post me your thoughts

Answer 1

This kind of behavior is not provided as a part of Joomla's default administration functions. You'll have to code it yourself and call that JS file when the module is opened in the backend. I would recommend you check the code used in Mod_news_pro by Gavick. The module loads a custom JS file that add a lot of custom functions and layout options that wasn't available in Joomla.

Answer 2

It's quite simple, just create a custom element checkout the official docs:
