HI @Srujan_Madderla, welcome to the Discourse Meta forum!
Discourse does not provide a way of doing this, but possibly the functionality could be added through a theme component or plugin. If you are new to Discourse, theme components allow you to add client side code to your site’s theme. Plugins can run server side code. It is generally easier to develop and install theme components than it is to install plugins.
I’m curious about the button to create an “Idea.” What is an Idea in your use case? Would it be a topic in a private category, a message sent to a group, or something else?
