    "description": "The VerticalLayout class arranges the layout elements in a vertical sequence, top to bottom, with optional gaps between the elements and optional padding around the sequence of elements.  <p>The vertical position of the elements is determined by arranging them in a vertical sequence, top to bottom, taking into account the padding before the first element and the gaps between the elements.</p>  <p>The horizontal position of the elements is determined by the layout's <code>horizontalAlign</code> property.</p>  <p>During the execution of the <code>measure()</code> method, the default size of the container is calculated by accumulating the preferred sizes of the elements, including gaps and padding. When <code>requestedRowCount</code> is set, only the space for that many elements is measured, starting from the first element.</p>  <p>During the execution of the <code>updateDisplayList()</code> method, the height of each element is calculated according to the following rules, listed in their respective order of precedence (element's minimum height and maximum height are always respected):</p> <ul> <li>If <code>variableRowHeight</code> is <code>false</code>, then set the element's height to the value of the <code>rowHeight</code> property.</li>  <li>If the element's <code>percentHeight</code> is set, then calculate the element's height by distributing the available container height between all elements with a <code>percentHeight</code> setting. The available container height is equal to the container height minus the gaps, the padding and the space occupied by the rest of the elements. The element's <code>precentHeight</code> property is ignored when the layout is virtualized.</li>  <li>Set the element's height to its preferred height.</li> </ul>  <p>The width of each element is calculated according to the following rules, listed in their respective order of precedence (element's minimum width and maximum width are always respected):</p> <ul> <li>If <code>horizontalAlign</code> is <code>&quot;justify&quot;</code>, then set the element's width to the container width.</li>  <li>If <code>horizontalAlign</code> is <code>&quot;contentJustify&quot;</code>, then set the element's width to the maximum between the container's width and all elements' preferred width.</li>  <li>If the element's <code>percentWidth</code> is set, then calculate the element's width as a percentage of the container's width.</li>  <li>Set the element's width to its preferred width.</li> </ul>  <p>The <code>&lt;s:VerticalLayout&gt;</code> tag inherits all of the tag attributes of its superclass and adds the following tag attributes:</p>  <pre>\\n &lt;s:VerticalLayout\\n <strong>Properties</strong>\\n gap=&quot;6&quot;\\n horizontalAlign=&quot;left&quot;\\n padding=&quot;0&quot;\\n paddingBottom=&quot;0&quot;\\n paddingLeft=&quot;0&quot;\\n paddingRight=&quot;0&quot;\\n paddingTop=&quot;0&quot;\\n requestedMaxRowCount=&quot;-1&quot;\\n requestedMinRowCount=&quot;-1&quot;\\n requestedRowCount=&quot;-1&quot;\\n rowHeight=&quot;<i>calculated</i>&quot;\\n variableRowHeight=&quot;true&quot;\\n verticalAlign=&quot;top&quot;\\n /&gt;\\n </pre>",
