+{call} {#language.function.call}
+======
+
+`{call}` is used to call a template function defined by the
+[`{function}`](#language.function.function) tag just like a plugin
+function.
+
+> **Note**
+>
+> Template functions are defined global. Since the Smarty compiler is a
+> single-pass compiler, The [`{call}`](#language.function.call) tag must
+> be used to call a template function defined externally from the given
+> template. Otherwise you can directly use the function as
+> `{funcname ...}` in the template.
+
+-   The `{call}` tag must have the `name` attribute which contains the
+    the name of the template function.
+
+-   Values for variables can be passed to the template function as
+    [attributes](#language.syntax.attributes).
+
+**Attributes:**
+
+   Attribute Name       Type       Required   Default  Description
+  ---------------- -------------- ---------- --------- ------------------------------------------------------------------------------------------
+        name           string        Yes       *n/a*   The name of the template function
+       assign          string         No       *n/a*   The name of the variable that the output of called template function will be assigned to
+    \[var \...\]    \[var type\]      No       *n/a*   variable to pass local to template function
+
+**Option Flags:**
+
+    Name    Description
+  --------- --------------------------------------------
+   nocache  Call the template function in nocache mode

+    {* define the function *}
+    {function name=menu level=0}
+      <ul class="level{$level}">
+      {foreach $data as $entry}
+        {if is_array($entry)}
+          <li>{$entry@key}</li>
+          {call name=menu data=$entry level=$level+1}
+        {else}
+          <li>{$entry}</li>
+        {/if}
+      {/foreach}
+      </ul>
+    {/function}
+
+    {* create an array to demonstrate *}
+    {$menu = ['item1','item2','item3' => ['item3-1','item3-2','item3-3' =>
+    ['item3-3-1','item3-3-2']],'item4']}
+
+    {* run the array through the function *}
+    {call name=menu data=$menu}
+    {call menu data=$menu} {* short-hand *}
+
+      
+
+Will generate the following output
+
+
+    * item1
+    * item2
+    * item3
+          o item3-1
+          o item3-2
+          o item3-3
+                + item3-3-1
+                + item3-3-2
+    * item4
