Create In-page Tabs

Creating Tabs in a Page

Create In-Page Tabs

If your theme or plugin only uses a single setting page but needs to separate certain contents into different areas, tabs are useful. This tutorial introduces a way to add tabs within a single page.


  1. Include the library
  2. Extend the library class
  3. Define the setUp() method
  4. In the setUp method, define a sub-page and in-page tabs. 
  5. Instantiate the extended class


Creating in-page tabs with Admin Page Framework

Include the library

The library file needs to be loaded.

Extend the library class

This time, let’s use APF_Tabs for the class name.

Define the setUp() method

In the setUp() method, we create a root page and  a sub page. For that we need to decide:

  1. the root page.
  2. the sub page title.
  3. the sub page slug.

We’ve covered this already in the previous tutorial.

To add in-page tabs, we use the addInPageTabs() method. Pass the belonging page slug to the first parameter and in-page tab definition argument array to the next parameters. In-page tab definition argument arrays require at least two keys: tab_slug and title. For more details refer to the manual.

Disable Page Heading Tabs and Enlarge the In-Page Heading Tabs

The framework supports three kinds of tabs: page heading tabs, in-page tabs, and form section tabs. The page heading tabs are automatically created when a sub-menu item is created and they are linked to the sub-pages/links. In-page tabs reside within a single page. Section tabs are for form sections so don’t worry about section tabs for now. In this tutorial, we are dealing with in-page tabs.

Since we just create a single page, we don’t need the page heading tabs. To disable page heading tabs, the setPageHeadingTabsVisibility() method is used.

Next, by default, in-page tabs use the h3 HTML tag and they are a bit smaller than page heading tabs using h2 tag. To increase the size by setting a custom tag, the setInPageTabTag() method is used.

Instantiate the extended class

Finally, we instantiate the class. Unless it is instantiated, it will do nothing.

  1. I have created a series of forms Using Admin Page Framwork. Each form is in a different Tab.
    I need to create some content (html) within each tab, before, and sometimes after the form entries.
    It is my understanding that a tab containing a form starts out:

    public function load_customize_my_mcc_tab_menu( $oAdminPage ) {
    array( .........


    And a tab containing content seems to start out:

    function content_my_tabs_my_tab_c( $sContent ) {
    return $sContent
    . 'Tab Content Filter'


    I have tried dozens of different way to add content to a oAdminPage function with zero luck.

    How does one accomplish this?

    1. Hi Derek,
