How do I develop step by step guided form filling to create a new record?

1. I have a requirement that using Platform UI, when I click on a custom UI action link on a form, instead of asking the user to fill out the whole record form completely in one view, I want to guide the user to fill out sections of the form in multi step flow.  

Example of it as reference is : Login as admin >> Self Service >> My Profile >> Reset a password UI action link...

What is the method to develop such navigated form entry?

2. Similarly what is a way to redirect to a custom form with custom fields on a custom table.

e.g   Login as Admin >> Self Service >> My Profile >> Change password UI action link...

Again this is all in Platform UI, not in Service Portal.

Thanks in advance.
