Orientation in React Tab component

29 Aug 202324 minutes to read

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.

      ASP.NET is an open-source server-side web application framework designed for web

      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
