# ember/template-require-context-role 💼 This rule is enabled in the 📋 `template-lint-migration` [config](https://github.com/ember-cli/eslint-plugin-ember#-configurations). ## `<* role><* role />` The required context role defines the owning container where this role is allowed. If a role has a required context, authors MUST ensure that an element with the role is contained inside (or owned by) an element with the required context role. For example, an element with `role="listitem"` is only meaningful when contained inside (or owned by) an element with `role="list"`. You may place intermediate elements with `role="presentation"` or `role="none"` to remove their semantic meaning. ## Roles to check Format: role | required context role - columnheader | row - gridcell | row - listitem | group or list - menuitem | group, menu, or menubar - menuitemcheckbox | menu or menubar - menuitemradio | group, menu, or menubar - option | listbox - row | grid, rowgroup, or treegrid - rowgroup | grid - rowheader | row - tab | tablist - treeitem | group or tree ## Examples This rule **allows** the following: ```hbs
Item One
Item Two
``` ```hbs
Item One
Item Two
``` This rule **forbids** the following: ```hbs
Item One
Item Two
``` ```hbs
Item One
Item Two
