How to set a div display condition if there is a specific module for the page (joomla)?

Question

PHP

How to set the display condition of a div with a mobile menu button in the output layout, on pages for which the output of the module (joomla) is set?

Answer 1

In the theme's index.php, check the existence of modules at a particular position using the $this->countModules('position') function. Further, if there are modules, set the body to a certain class, based on which you will hide \ show this div in css.
Or, based on the above condition, directly in index.php determine whether to display the div or not.

if($this->countModules('position')) :
    // тут выводите нужный html, если модули есть
endif;
