<p><code>opt:section</code> is the basic section instruction used to display flat, linear lists and supports all the section basic features. Inside the <code>opt:section</code> we define the layout of a single list element:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;ul<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:section</span> <span style="color: #000066;">name</span>=<span style="color: #ff0000;">&quot;categories&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>{$categories.name}, {$categories.productCount}<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:section<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/ul<span style="color: #000000; font-weight: bold;">&gt;</span></span></span></pre>

<h2>Empty lists</h2>

<p>We may define the optional content to be displayed if the list is empty with the <code>opt:sectionelse</code> tag:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;ul<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:section</span> <span style="color: #000066;">name</span>=<span style="color: #ff0000;">&quot;categories&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
        <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>{$categories.namae}, {$categories.productCount}<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
        <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:sectionelse<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
        <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>We are sorry, there are no categories in the system.<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
        <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:sectionelse<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:section<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/ul<span style="color: #000000; font-weight: bold;">&gt;</span></span></span></pre>

<p><code>opt:sectionelse</code> must be located directly within <code>opt:section</code>, but it is up to you, whether you put it before or after the content.</p>

<p><code>opt:sectionelse</code> is disabled, if the section is used together with <code>opt:show</code>. In this case, the alternative message can be declared with <code>opt:showelse</code>:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:show</span> <span style="color: #000066;">name</span>=<span style="color: #ff0000;">&quot;categories&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;ul<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:section<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
        <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>{$categories.name}, {$categories.productCount}<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/li<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:section<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/ul<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:showelse<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
