Step in a list. The zem\_nth plugin adds a conditional tag to [Textpattern CMS](http://textpattern.com), which can be used to matches every nth item in a group of items based on the given step and group of. This tag works similarly to the [:nth-child](https://developer.mozilla.org/en-US/docs/CSS/:nth-child) pseudo-selector found in CSS.

Installing
----------

[](#installing)

Using [Composer](http://getcomposer.org):

```
$ composer require rah/zem_nth:*
```

Or [download](https://github.com/gocom/zem_nth/releases) a plugin package.

Tag attributes
--------------

[](#tag-attributes)

```

	...every third...

	...first and second...

```

The tag can also be used as a single, self-closing tag to return the current counter value:

```

```

Attributes are as follows:

**step**
The step to jump.
Example: `step="2"` Default: `"2"`

**of**
Step of how many.
Example: `off="4"` Default: `undefined`

**id**
The identifier assigned to the counter. By default counters are identified by their contents. If you need multiple counters for identical code blocks, you can use the `id` attribute to set your own identifier to prevent collisions. The `id` attribute can also be used to connect two counters with different contents that wouldn’t normally be connected.
Example: `id="article_sidebar_stripes"` Default: `undefined`

**start**
The value the counter starts from. This allows resuming a previous counter, or just to add padding.
Example: `start="25"` Default: `"0"`

**reset**
If set to `1`, resets the current counter back to the starting value set with `start`.
Example: `reset="1"` Default: `"0"`
