There is a form in it to be a field for entering regions()
On the basis of them should show the cities of these regions in the field below()

I think it ajax

But I’m not experienced this

Can you recommend what to read for it or (halpers rails for this task)

P.S Thanks for wathing

#2

you need to do that in javascript, I don’t think any part of Rails does that for you.

check out http://www.sanwebe.com/2013/05/select-box-change-dependent-options-dynamically

for a good explanation

there may be a rails gem or plugin that can help you, but I do not know of what specifically for that purpose.
