How to make a range of issuing the list in php?

There's a list, with a visibility range of 10 points, everything else is hidden and reveals on the "more" button. Upon issuance of a particular article from the database (ACC id), highlighted a particular paragraph in the list. What else you want to implement - even if the item would be 11, 12, 13...28 - it came up in the list of visibility (10 points), respectively, and the other following behind him too. Who would you recommend?
