Re-vamped the navbar docs to fix incorrect info about icon positioning and theming. Fixes #1858, Fixes #1797, Fixes #2667, Fixes #1180, Fixes #2373
The docs incorrectly stated that the icon position could be set per link, but this is intended as a global setting for the navbar parent. This is working as designed and helps with visual consistency. If icon positioning needs to be be adjusted per link, you will need to manually apply the right classes through JS and may need to tweak CSS because top/bottom and left/right positions have different heights.

<p>jQuery Mobile has a very basic navbar widget that is useful for providing up to 5 buttons with optional icons in a bar, typically within a header or footer. There is also a <a href="footer-persist-a.html">persistent nav bar</a> variation that works more like a tab bar that stays fixed as you navigate across pages.</p>
|
||||
<p>A navbar is coded as an unordered list of links wrapped in a container element that has the <code> data-role="navbar"</code> attribute. To set one of links to the active (selected) state, add <code>class="ui-btn-active"</code> to the anchor. In this example, we have a two-button navbar in the footer with the "One" item set to active:</p>

<pre><code>
|
||||
<div data-role="footer">
|

<div data-role="navbar">

|
||||
<li><a href="a.html" class="ui-btn-active">One</a></li>

<h2>Theming navbars</h2>
|
||||
|
||||
<p>Navbars can be set to any theme color by <code> data-theme</code> attribute to the links and specifying any theme swatch.</p>
|
||||
<p>Navbars inherit the theme swatch from their parent container, just like buttons. If a navbar is placed in header or footer toolbar, it will inherit the default toolbar swatch (A) for bars unless you set this in the markup. </p>
|
||||
<p>Here are a few examples of navbars in various container swatches automatically inheriting their parent's swatch letter. Note that in these examples, instead of using a <code>data-theme</code> attribute, we're manually adding the swatch classes to apply the body swatch (<code>ui-body-a</code>) and the class to add the standard body padding (ui-body), but the inheritance works the same way:</p>
