Change Theme

I have application and I have multiple theme, but I want change theme when I click button

Hi Afkar,

Unfortunately that's not possible.

Will this ever be possible?

Hi Kabir,

I believe it is actually possible for a long time, but definitely not simple to implement. It will require a fair amount of effort and a good understanding of how the platform works, how HTML and CSS loading works and how to manipulate those through OutSystems logic.

Darn, I was hoping there was just an easy way to use Javascript to change aspects of the css.

This gave me some hope but i'd need to be a lot better with Javascript to be able to figure out how this could be implemented app wide.
