Steps to reproduce the issue

Install the blog sample data for the front end, and then go on to creating a menu item, say in the main menu, at first you'll find the items of all the menus listed, and if you save and close it and get back to it and again look at the parent category you'll only find the sub-menus that belong to the main menu, but if you wish to change the type of menu you say I want to switch to main menu blog I don't see the drop-down list updated.

Expected result

In my opinion, the drop-down menu should be updated with every change in the menu category.

Actual result

System information (as much as possible)

4.2.7-dev
