Hi,

Presently I am using drop down with following function  
\<%= task\_form.collection\_select :task\_type,  
@task\_types, :id, :display\_value %\>  
It basically gives me ability to have drop down based on an array of  
objects

I am looking for a similar radio buttons function which will allow me  
to only give it an array and the GUI will render it into radio  
buttons.

Can someone please assist?

It doesn’t look like anyone’s answered this so far… You’ll have to  
write your own helper to provide this functionality. A place to begin  
your research on how to implement it is in the Rails code itself,  
actionpack/lib/action\_view/helpers/form\_options\_helper.rb, and look at  
how collection\_select is implemented. If you come up with a great  
solution, a plugin, gem or fork or Rails would be great to share it  
back.
