i am using following code for drop down.

\<%= select\_tag(‘abc’,"" +  
options\_from\_collection\_for\_select(@priorarr,:Id,:Priority,:selected =\>  
params[:cs\_priority])) %\>

it is giving me one drop down with the values populated from the  
“@priorarr” array.

Now i want to use this value inside my controller class.

i am using params[:cs\_priority]…  
but not working…

please help me…in reading value from the drop down…

Thanks in advance…

Take a look in your logs at the params your app is receiving and  
you’ll see that it’s accessible as params[:abc] (since ‘abc’ is the  
first parameter you’re passing to select\_tag)
