So, I’m going one step further with this, based on @Mark_Pederson suggestion.
I’ve created a component made of a couple of divs and elements looking like this.
→ I’ve created component properties for each elements and bound them with the actual data.
→ In my page, I use an array of data containing all my infos (eventually will be a collection in my DB) and bind it to the main page div.
→ I link the button to an increment variable that look up the current item in the array bound to the display property.
There you go ! Easy reusable multi-step form or for whatever process you need !
EDIT : Haven’t done it yet, but this will also make it easy to display a dynamic progress bar from item.index/data.length
