NetMRI enables custom information to be applied to the Inventory pages for any category within **Network** **Explorer** > **Inventory** > (**Devices**, **Interfaces**, **OSs**, and **Models**.).

For example, under **Devices**, all four categories of table information—**Devices**, **Device** **Components**, **Connected** **End** **Hosts**, and **Connected** **IP** **Phones** — can display custom data to provide further insight into the state and details of a given device, host, or another inventory component.

Some custom fields, depending on the information provided by them, may or may not be applicable to specific tables of information.

To add custom fields into tables within Network Explorer's Inventory pages, do the following:

1. Under **Network** **Explorer** > **Inventory**, select any of the four categories of information (**Devices**, **Interfaces**, **OSs**, or **Models**.)
2. Choose any of the sub-categories of information and the corresponding table appears. For example, under Devices, choose **Device** **Components** (you are not limited to this choice).
3. Move the mouse over any column in the table, and click the down arrow at the right end of the column heading.
4. In the drop-down menu, hover over **Columns**.
5. In the **Columns** submenu, check the custom field column(s) you want to appear in the table. The table will update to display the new column of data.
