How to create html code so that after submitting an application, it is redirected to a thank you page?

Question

CRM

I have a very difficult situation, they created a site for me, but it was not completely created, and then the contractor disappeared, and now I need to create redirects for customers to the thank you page after submitting the application. I use my CRM system for processing applications, it does not have the ability, like in Bitrix 24, to redirect to any page after sending the application, there is only an input text that is visible after sending. here is the link <iframe width="600" height="850" src=" https://domen.ru/forms/wtl/02d617ce1d14f6b0aaa46ca... "frameborder="0" allowfullscreen> which gives it to me crm system

html does not redirect anyone to anywhere. Probably the implementation of redirection should be on the server using the programming language in which you have written cms.
no, it's a very simple situation. And quite trivial. Solved by looking for another artist.
what the heck is this about. I read and did not understand anything. The words are familiar, but the layout is apparently random. Approximately it looks like this: "I use my bemeve car to carry people, but it doesn’t have the ability to throw it up like a KAMAZ, there it’s only teleport with the steering wheel and forward, and if the gears on the left turn the cardan - then where is the door?"
"here" is where?
PS: I highly recommend to involve a specialist, show him the code and describe in more detail what you need. By the way, after reading the question, in my opinion, I understood where the last developer had gone. His brain exploded. It might be worth considering working through a project manager.

For the submission form, direct the action to the thank you page and process the submission of the application there. This is the easiest way, given that you did not give a link)
