AdminLTE uses all of Bootstrap 3 components. It's a good start to review the Bootstrap documentation to get an idea of the various components that this documentation does not cover.
If you go through the example pages and would like to copy a component, right-click on the component and choose "inspect element" to get to the HTML quicker than scanning the HTML page.
The main header contains the logo and navbar. Construction of the navbar differs slightly from Bootstrap because it has components that Bootstrap doesn't provide. The navbar can be constructed in two ways. This is an example for the normal navbar and next we will provide an example for the top nav layout.
Top Nav Layout. Main Header Example.
To use this main header instead of the regular one, you must add the
layout-top-nav class to
the body tag.
Top navbar example can be found in this demo page.
