To maximise screen space and for better mobile performance, categories, product search and additional pages (if enabled) are active via an off canvas
menu. Click the
icon to display the menu. Click anywhere off the menu to hide.
State is maintained, so for example, if the categories tab is clicked, on page reload this is still the selected option. If you want to
have the sub categories displayed too, set the 'SHOW_MENU_SUB_CATS' constant to 1 in the 'control/options.php' file.
For the price search, initial parameters can be changed in the 'control/options.php' file.
