Need Vanilla JS Expert

This is for my electron app

Current setup is vanilla js, html, css

Setup a local db inside electron

Setup a steps process from index.html where some inputs are inside a modal..

after inputs are filled click create and another page is generated where those inputs are saved and can be updated ..

example: use steps and name it A .. after click create, a page for A is created .. use steps again and name it B .. after click create, a page for B is created and so on..

From index.html A, B and so on can be deleted and opened

Not sure if it will be individual pages that are created or how the setup should be
