Problem with Unorganized content on page
Since you tagged your question with "Views", I assume your screenprint is created via a view. And the view itself relates to some sort of entities like nodes, products, whatever.

If that's the case, decide about the "sort field" that you want to use in your view, and adapt it to fit your needs. If you cannot find any appropriate field that you want to use for such sorting, then just add an extra field (named something like sequence nr, and like an integer of say 4 digits). Then edit each of your entities to assign a relevant sequence nr, and use that as the sort field for your view.

BTW, this is true for pretty much any Drupal release.

PS: as per the "drag the item" in your question, it could well be that you're using the "DraggableViews" module to create such view.
