A Coral.TabList creates a set of tab elements. This is typically used with the Coral.TabView wrapping container, along with a Coral.PanelStack, to create a tabbed UI element. The target attribute is used to determine what element a Coral.TabList is controlling.

See the Coral.TabView documentation for a complete example of this pattern.

Collection API

The TabList implements the Collection API as a way to manipulate the items. It provides add(), remove(), clear(), and getAll(), as well as their corresponding events to keep track of the items. Check Coral.Collection for more information.

add(item, insertBefore)

The following code adds an item using the JavaScript constructor. After an item is added a coral-collection:add event will be triggered. 

var tabList = new Coral.TabList();
var item = new Coral.Tab();
tabList.items.add(item);

Add also allows using an object that represents the item. All values will be set using the multiple value set provided by the Coral.Component class. 

var tabList = new Coral.TabList();
tabList.items.add({
  label: {
    textContent: 'Tab'
  },
  icon: '',
  invalid: false,
  disabled: false,
  selected: false
});

remove(item)

Item removal is done in a similar fashion. After any removal, the TabList will trigger a coral-collection:remove event. 

tabList.items.remove(item);
