How to do this ?

[Fahim Patel]

I wish to select one value from drop down and second drop down should shows those values which are related to that  selected value 

from first drop down.

It should be dynamic ?

Did i have to use Ajax ?

It should be done using javascript. Or if you want to get the values of second dropdown from server then you have to use AJAX.

I don't have specific tutorials to follow. Google is your best companion for this purpose. If you can share some of your code then I can help you to take a start.

code :

Area

<%= f.select :area_id, Area.all.collect {|p| [ p.name, p.id ] }, :class=>"small"  %>

Milk Mans

<%= f.select :milkman_id, Milkman.all.collect {|p| [ p.name, p.id ] }, :class=>"small"  %>

When i select any area then i should see only those milkmans of that area.

Till now i getting all milkmans in my select box.

I understood the question but I don't know that why I am unable to answer this. I think you should provide me the HTML code which is shown in page source after the page is loaded. It's embarrassing for me that I am unable to understand the code in your html.erb file.
