The K2 Category Dashboard is the centre for your K2 category management and the layout is relativley self explanatory.
This guide is relevant to both V2.4.1 and V2.5

The view is split in to several columns across the page and so I shall describe from left to right.

• # Column

• Tick Box Column
  Used to select an item so that an additional function can be carried out.

  Displays the titles of the K2 categories that have been created.
• Order Column
