Syntax

<txp:category_list />

The category_list tag can be used as either a single tag or container tag which is used to produce a list of linked categories.

Attributes

Tag will accept the following attributes (case-sensitive):

active_class="class name" v4.0.4+
HTML class attribute to be applied to the active or current link in a list. Only works in the single tag without the form attribute.
Default: unset.
categories="category name(s)" v4.0.4+
Comma-separated list of categories to include, displayed in the order specified (unless overridden by sort attribute). Use category names not titles here - note that Textpattern automatically converts the names to lowercase and converts spaces to hyphens when they are created.
Default: unset (all categories).
children="integer" v4.7.0+
Can limit the list depth to defined levels below the parent category.
Values: 0 (no children, i.e. only show one level below the parent) or n (show all nested categories and ‘flatten’ the list at the level n).
Default: 1.
exclude="category name(s)" v4.0.4+
List of category names which will be excluded from the list. categories takes precedence over exclude.
Default: unset.
form="form name" v4.0.7+
Use specified form to process each included category.
Default: unset.
html_id="id" v4.6.0+
The HTML id attribute applied to the wraptag, if set.
Default: unset.
limit="integer" v4.6.0+
The number of articles to display.
Default: 0 (no limit).
offset="integer" v4.6.0+
The number of articles to skip.
Default: 0.
parent="category name"
Return only specified category and its children categories. Accepts comma-separated list of values.
Default: unset.
section="section name" v4.0.4+
Restrict to articles from specified section(s).
Values: (comma separated list of) section name(s).
Default: unset, retrieves from all sections.
sort="sort value(s)"
How to sort the resulting category list. Specify a value from the ones below, followed by a space and then add either asc or desc to sort in ascending or descending order, respectively.
Values:
id.
name.
parent.
rand() (random).
title.
type.
Default: name asc.
this_section="boolean" v4.0.4+
Link to currently active section (overrides section attribute).
Values: 0 (no) or 1 (yes).
Default: 0.
type="category type"
Values: article, image, link, file.
Default: article.

Common presentational attributes

These attributes, which affect presentation, are shared by many tags. Note that default values can vary among tags.

break="value"
Where value is an HTML element, specified without brackets (e.g. break="li") or some string to separate list items.
Default: br (but see break cross-reference for exceptions).
breakby="integer" v4.7.0+
Used to group list items when separating by break. Possible values are lists of integers, like 2 (groups of 2 items) or 1,2 (alternate groups of 1 and 2 items).
Default: 1 (actually unset).
class="class name"
HTML class to apply to the wraptag attribute value.
Default: tag name or unset (see class cross-reference).
label="text"
Label prepended to item.
Default: unset (but see label cross-reference for exceptions).
labeltag="element"
HTML element to wrap (markup) label, specified without brackets (e.g. labeltag="h3").
Default: unset.
wraptag="element"
HTML element to wrap (markup) list block, specified without brackets (e.g. wraptag="ul").
Default: unset (but see wraptag cross-reference for exceptions).

Examples

Example 1: Labelled category list

<txp:category_list label="Categories" wraptag="p" break="br" />

Example 2: As an unordered list

<txp:category_list break="li" wraptag="ul" />

Example 3: Set active class using the container tag

<txp:category_list wraptag="ul" break="">
    <li<txp:if_category name="<txp:category />"> class="active"</txp:if_category>>
        <txp:category title="1" link="1" />
    </li>
</txp:category_list>

This code will add class="active" to the <li> element around the current viewed category in the list, allowing your to style it with CSS as desired.

Other tags used: category, if_category.
