knowledge:categoryList | Standard Visualforce Component Reference | Visualforce Developer Guide

A loop on a subset of the category hierarchy. The total number of categories displayed in a page can’t exceed 500.

You must have access to the category you set as rootCategory to get a list of any categories. To list categories available to a user, see the Knowledge Support REST APIs.

Example

List descendents of the ‘phone’ category. ‘phone’ is in the ‘product’ category group.

1<select name="category">
2    <knowledge:categoryList categoryVar="category" categoryGroup="product" rootCategory="phone" level="-1">
3        <option value="{!category.name}">{!category.label}</option>
4    </knowledge:categoryList>
5</select>
