I have a region with menus, a menus displays depending on the url example if on the about page(sitename/about-us), display about menu and links as a sub menu.
It works, but the problem is after navigating through the site a couple of times, the region caches. is the anyway i can clear the regions cache on page reload.
I tried the below in my .theme
/**
* Implements hook_preprocess_HOOK() for block.html.twig.
*/
function themename_preprocess_block(&$vars) {
//the menu block id name in the region
if ($vars['derivative_plugin_id'] == 'submenu') {
//-- This stops the block being cache in drupal 8
$vars['#cache']['max-age'] = 0;
}
}
also tried
/**
* Implements hook_preprocess_HOOK() for block.html.twig.
*/
function themename_preprocess_block(&$vars) {
if ($vars['derivative_plugin_id'] == 'theme-block-branding') {
//-- This stops the block being cache in drupal 8
$vars['#cache']['max-age'] = 0;
}
}
not sure what steps I can follow to achieve the above
