<h2>Dynamically update nav containers</h2>

<h3>Description</h3>

<p>Functions for dynamically updating nav containers (e.g., select, insert, and
remove nav items). These functions require an <code>id</code> on the nav container to be
specified.
</p>

<h3>Usage</h3>

<pre>
nav_select(id, selected = NULL, session = getDefaultReactiveDomain())

nav_insert(
  id,
  nav,
  target = NULL,
  position = c("after", "before"),
  select = FALSE,
  session = getDefaultReactiveDomain()
)

nav_remove(id, target, session = getDefaultReactiveDomain())

nav_show(id, target, select = FALSE, session = getDefaultReactiveDomain())

nav_hide(id, target, session = getDefaultReactiveDomain())
</pre>

<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>id</code></td>
<td>
<p>a character string used to identify the nav container.</p>
</td></tr>
<tr valign="top"><td><code>selected</code></td>
<td>
<p>a character string used to identify a particular <code><a href="nav.html">nav()</a></code> item.</p>
</td></tr>
<tr valign="top"><td><code>session</code></td>
<td>
<p>a shiny session object (the default should almost always be used).</p>
</td></tr>
<tr valign="top"><td><code>nav</code></td>
<td>
<p>a <code><a href="nav.html">nav()</a></code> item.</p>
</td></tr>
<tr valign="top"><td><code>target</code></td>
<td>
<p>The <code>value</code> of an existing <code>nav()</code> item, next to which tab will be added. If removing: the <code>value</code> of the <code>nav()</code> item that you want to remove.</p>
</td></tr>
<tr valign="top"><td><code>position</code></td>
<td>
<p>Should <code>nav</code> be added before or after the target?</p>
</td></tr>
<tr valign="top"><td><code>select</code></td>
<td>
<p>Should <code>nav</code> be selected upon being inserted?</p>
</td></tr>
</table>
