I want to create a list like below but i dont know exactly what name is it .

My menu

  1. Top
  2. Content 1
  3. Content 2
  4. Bottom

When i click 1,2,3,4 it will scroll to the match content.
And when i scroll page its will show the match . example when i read content2 the menu will make “Content 2” to bold text
