Remove pages from header menu

Hi, can someone tell me how to remove all these pages from Header region. There are 10 pages and all of them are showing on header area. I just want to show only 2-3 on Header? I tried going on customisation of theme but it’s not very helpful unless I am doing something wrong??

Hi,

Yes, you can remove these pages in WP Dashboard > Pages.

​I hope this is helpful to you.
