如何在Joomla中更改文章的布局？

Question

Is it possible in Joomla to override whole layout for article (not only article component layout)? I have two columns website (with modules in right column) but for some articles i need one column design.

Answer 1

Articles Associated with a Menu Item

Edit the right column modules in Extensions -> Modules, and go to the Menu Assignment tab to disable modules on particular pages so that the sidebar collapses and the full width of the template will be used by the main content.

Articles Not Associated with a Menu Item

As far as I am aware, there is no provision for an article CSS class in the same way there is a page class for a menu item.

A crude way to implement this would be to install the free or paid version of Regular Labs Sourcerer or similar so that you can include some code in the article to dynamically add some CSS like this or similar:

<?php
$document = JFactory::getDocument();
$style = '.sidebar {'
          . 'display: none;'
          . '}'
          . '.main-content {'
          . 'width: 100%;'
          . '}';
$document->addStyleDeclaration($style);
?>

Even better, add the code to a custom HTML module (remember to set "Prepare Content" to "Yes" under the Options tab) with a custom module position such as full-width and then include the following code in the articles you wish to make full width:

{loadposition full-width}
