Assistive technologies utilize ARIA tags to help give the user the context of an item in the content. Some role values (the parents) must contain other role(s) (the children) so the intended accessibility of the role can function as expected.

Elements utilizing certain ARIA roles require that the contents within the element also have certain roles. These issues can be flagged in both directions, i.e. parents that must have a child and children that must have a parent element.

The WAI-ARIA Overview document provides detailed information on what is required for each of these most common parent roles flagged for parent-child relationship issues in DubBot. For the parent roles listed below, look in the Characteristics table, in the Required Owned Elements row for the choices of valid child roles that the parent role should own.

A list of all roles with their accompanying definitions can be found in section 5.4 Definition of Roles of the ARIA Overview document.

An unordered list (ul) with role="tablist" should contain elements with the role="tab".

HTML example utilizing tablist:

Sometimes a role is added to an HTML tag that overrides the inherent role of the tag.

An example, <ul role="tablist">. Assigning the role="tablist" to the unordered list <ul> overrides the inherent role of the content from an unordered list to a tablist.
