Class \Prado\Web\UI\WebControls\THead
THead displays a head element on a page. It displays the content enclosed in its body and the page title set by the \Prado\Web\UI\WebControls\setTitle property. In addition, stylesheets and JavaScripts registered via TClientScriptManager::registerStyleSheet, TClientScriptManager::registerStyleSheetFile TClientScriptManager::registerHeadJavaScript, and TClientScriptManager::registerHeadJavaScriptFile will also be displayed in the head. THead also manages and displays meta tags through its \Prado\Web\UI\WebControls\getMetaTags property. You can add a meta object to the collection in code dynamically, or add it in template using the following syntax,
<com:THead>
<com:TMetaTag HttpEquiv="Pragma" Content="no-cache" />
<com:TMetaTag Name="keywords" Content="Prado" />
</com:THead>
Note, TPage has a property \Prado\Web\UI\TPage::getHead that refers to the THead control currently on the page. A page can have at most one THead control. Although not required, it is recommended to place a THead on your page. Without a THead on the page, stylesheets and javascripts in the current page theme will not be rendered.
