# Plugin {#plugin}

## Filter by categories {#filter-by-categories}

The listed events in a plugin can be filtered by categories.
The categories can be selected in the categories tab of the content element (not in the plugin options) or in the Plugin Configuration.

### Category conjunction {#category-conjunction}

<!-- TODO: no Markdown rendering for "versionadded" -->

It is possible to define how multiple categories are handled.
If the event requires at least one (OR) or all (AND) categories to be displayed.![Category conjunction setting with 'all', 'or' and 'and'](../../Images/User/plugin-category-conjunction.png)

-   **categoryConjunction**

    -   *type:* string
    -   *Default:* or
    -   *Scope:* Plugin

    The category conjunction defines if and how the categories are treated.
    If no category is configured, no filter is applied (all events are shown).

    -   **`[all]` (Don't care, show all)**

        There is no restriction based on categories, even if categories are defined.

    -   **`[or]` (Show items with selected categories (OR))**

        All event records which belong to at least one of the selected categories are shown.

    -   **`[and]` (Show items with selected categories (AND))**

        All event records which belong to all selected categories are shown.
