Header in the all pages

Please, how can I create a header with menu items and a clickable notification element (as a bell)? To use it in all pages.
thanks a lot.

If you are building a Multi page app, you could use a reusable element that includes both the header and the menu itself, and just place that into each page.

This is just one way, in fact there are many ways to do it, depending on your exact needs.

i believe it’ll be enought.
tks so much!
