WAI-ARIA accessible tabs for Ember.
npm install ivy-tabs


A group of Ember.js Components that interact to create a [WAI-ARIA tab] interface.
Special thanks to [ic-tabs], which this addon is based on.
**NOTE: This addon uses contextual components, which require Ember >= 2.3. For
older versions of Ember, use the 1.x release series of this addon.**
* Ember.js v3.12 or above
* Ember CLI v2.13 or above
* Node.js v10 or above
``sh`
$ ember install ivy-tabs
`handlebars
{{#ivy-tabs selection=selection as |tabs|}}
{{#tabs.tablist tagName="ul" as |tablist|}}
{{#tablist.tab "TabA" on-select=(action (mut selection))}}Foo{{/tablist.tab}}
{{#tablist.tab "TabB" on-select=(action (mut selection))}}Bar{{/tablist.tab}}
{{#tablist.tab "TabC" on-select=(action (mut selection))}}Baz{{/tablist.tab}}
{{/tabs.tablist}}
{{#tabs.tabpanel "TabA"}}
{{#tabs.tabpanel "TabB"}}
{{#tabs.tabpanel "TabC"}}
Some things to note:
* Associations between tabs and panels are explicitly defined by the "models"
(the first positional parameter) given to them. In the above example, the
given tab models are "TabA", "TabB", and "TabC". This model could be any
JavaScript Object that you'd like, they are not required to be strings.
* An
on-select action is sent when a tab is selected. As an argument, it
receives the model defined on the tab (for example, when the Foo tab is
selected, the on-select event will carry "TabA" as an argument).$3
ivy-tabs does not make any assumptions about how you will present your tabs.
Specifically, this means that ivy-tabs will not automatically hide unselected
tab panels. Rather, you should update your application styles to reflect your
needs.
In an ideal world, your application would carry a CSS rule similar to the
following:
`css
[aria-hidden="true"] {
display: none;
}
`If, for some reason, your target audience does not support CSS attribute
selectors, you may also opt to instead rely on the ivy-tabs classes by
defaulting all panels to being hidden and only displaying the active panel
using CSS rules similar to (remember,
.active will be different if you
override the activeClass property of your ivy-tabs-tabpanel):`css
.ivy-tabs-tabpanel {
display: none;
}.ivy-tabs-tabpanel.active {
display: block;
}
