// TODO: Combine tabset with route-tabset, so that we can:
// - have similar interface
// - easy to migrate from one to another
// - can mix them both (route/content tab)
/**
*
* Dynamic tabset component.
* @stacked-example(Showcase, tabset/tabset-showcase.component)
*
* Basic tabset example
*
* ```html
* <nb-tabset>
* <nb-tab tabTitle="Simple Tab #1">
* Tab content 1
* </nb-tab>
* <nb-tab tabTitle="Simple Tab #2">
* Tab content 2
* </nb-tab>
* </nb-tabset>
* ```
*
* ### Installation
*
* Import `NbTabsetModule` to your feature module.
* ```ts
* @NgModule({
* imports: [
* // ...
* NbTabsetModule,
* ],
* })
* export class PageModule { }
* ```
* ### Usage
*
* It is also possible to set a badge to a particular tab:
* @stacked-example(Tab With Badge, tabset/tabset-badge.component)
*
* and we can set it to full a width of a parent component
* @stacked-example(Full Width, tabset/tabset-width.component)
*
* `tabIcon` should be used to add an icon to the tab. Icon can also be combined with title.
* `responsive` tab property if set allows you to hide the title on smaller screens
* (`tabs-icon-only-max-width` property) for better responsive behaviour. You can open the following example and make
* your screen smaller - titles will be hidden in the last tabset in the list:
*
* @stacked-example(Icon, tabset/tabset-icon.component)
*
* It is also possible to disable a tab using `disabled` property:
* @stacked-example(Disabled Tab, tabset/tabset-disabled.component)
