    1. CODo you really want to do all this work with mysql for a menu? The menu is usually the same across the entire site and rarely changes. So it makes sense, I think, to just hard-code it in HTML. It only makes sense to put it in the database, I think, if you're going to be frequently changing it, AND if you are creating some kind of "backend" to give your end user a way to edit the menu structure. Otherwise, why use a database for this?

    2. COYes Buttle. The client wants an option to add more pages in future. So I had to create a table for the pages and menu

    3. CO@ButtleButkus that's what I was thinking of. Usually menu items are usually the same except for maybe changing something login/logout and register/login.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
