Orientation

This section explains about modifying the position and modes of Tab header.

It allows placing the header section inside the Tab component at different positions by using the headerPlacement property. The available positions are as follows:

  • Top: Tab header items can be arranged horizontally, and their content can be placed after the header.
  • Bottom: Tab header items can be arranged horizontally, and their content can be placed before the header.
  • Left: Tab header items can be arranged vertically, and their content can be placed after the header.
  • Right: Tab header items can be arranged vertically, and their content can be placed before the header.

It is also adaptable to the available space when the tab items exceed the view space. You can customize the modes by using overflowMode property. The available modes are as follows:

  • Scrollable
  • Popup

      HyperText Markup Language, commonly referred to as HTML, is the standard markup
language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone
technology, used by most websites to create visually engaging web pages, user interfaces
for web applications, and user interfaces for many mobile applications.[1] Web browsers
can read HTML files and render them into visible or audible web pages. HTML describes
the structure of a website semantically along with cues for presentation, making it a
markup language, rather than a programming language.

enterprise servers and supercomputers. While less common, Java applets run in secure, sandboxed environments to
provide many features of native applications and can be embedded in HTML pages.

cross-platform implementations of the Common Language Infrastructure (CLI) and Common
Language Specifications (often called Microsoft .NET). With a C#-shared codebase,developers
can use Xamarin tools to write native Android, iOS, and Windows apps with native user interfaces
and share code across multiple platforms.[5] Xamarin has over 1 million developers in more
than 120 countries around the World as of May 2015.

ASP.NET is an open-source server-side web application framework designed for web
development to produce dynamic web pages. It was developed by Microsoft to allow programmers
to build dynamic web sites, web applications and web services. It was first released in January
2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft Active Server
Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing
programmers to write ASP.NET code using any supported .NET language. The ASP.NET SOAP extension
framework allows ASP.NET components to process SOAP messages.

The ASP.NET MVC is a web application framework developed by Microsoft, which implements
the model–view–controller (MVC) pattern. It is open-source software, apart from the ASP.NET Web
Forms component which is proprietary. In the later versions of ASP.NET, ASP.NET MVC, ASP.NET Web
API, and ASP.NET Web Pages (a platform using only Razor pages) will merge into a unified MVC 6.
The project is called ASP.NET vNext.

JavaScript (JS) is an interpreted computer programming language. It was originally
implemented as part of web browsers so that client-side scripts could interact with the
user, control the browser, communicate asynchronously, and alter the document content that
was displayed.[5] More recently, however, it has become common in both game development
and the creation of desktop applications.
