Pagebreak in multistep form ?

Right from reading the description of these two modules, it seems that you can use these for your specific requirements -
https://www.drupal.org/project/webformnavigation →
https://www.drupal.org/project/webform_skip →
However, the "Webform Skip" module does not seem to be maintained. Please try the "Webform Navigation" module.

#2 - I can use this webformnavigation module. Thank you. But it does not solve my problem.

The webform is set up with four pages, within every page, i have several steps. Each step is a textarea,. and i want to go through these steps within the page with a prev / next button, like when changing pages

You have to write custom code to support this. You might want to try using webform cards. @see https://www.youtube.com/watch?v=bDugc2gWQnw
