#### Overview

Sometimes you may want to change some attribute for a number of items at
once. Instead of opening each individual item for editing, you may use
the mass update function for that.

#### Using mass update

To mass-update some items, do the following:

-   Click on *Mass update* below the list
-   Navigate to the tab with required attributes (*Item*, *Tags* or
    *Preprocessing*)
-   Mark the checkboxes of the attributes to update
-   Enter new values for the attributes

The *Tags* option allows to:

-   *Add* - add specified tags to the items (tags with the same name,
    but different values are not considered 'duplicates' and can be
    added to the same item).
-   *Replace* - remove the specified tags and add tags with new values
-   *Remove* - remove specified tags from the items

User macros, {INVENTORY.\*} macros, {HOST.HOST}, {HOST.NAME},
{HOST.CONN}, {HOST.DNS}, {HOST.IP}, {HOST.PORT} and {HOST.ID} macros are
supported in tags.

Mark the checkbox next to *Preprocessing steps* to activate mass update for preprocessing steps.

The *Preprocessing* mass update allows to:

-   *Replace* - replace the existing preprocessing steps on the items with the preprocessing steps specified below
-   *Remove all* - remove all preprocessing steps from the items

When done, click on *Update*.
