Question

Need a joke like this. What is this functionality called? And how to implement?

Answer 1

as a rule, layout in terms of html is one common, and css styles are completely different, several options, i.e. when you click on the button, the class of the list output block simply changes and the browser will redraw everything itself

Answer 2

You get cookies of the display type, compare, set the parameter value

if($cookie_view_ind == 'table')
{
$arParams['LIST_PRODUCT_ROW_VARIANTS']
}

link has href="?view=table"
