Alter contextual links

Question

I'm trying to alter custom blocks contextual menu. In particular I need to remove "Configure block" and "Delete". Is there any way to achieve this?

Answer 1

The correct way to alter contextual links is to use hook_contextual_links_alter.

In your case, it should look something like:

function my_module_contextual_links_alter(array &$links, $group, array $route_parameters) {
  if ($group === 'block') {
    // Hide Configure Block option.
    unset($links['entity.block.edit_form']);
  }
}

The contextual links are heavily cached in the browser, therefore you need to make sure that the browser session cache is cleared - window.sessionStorage.clear(); - source.

Answer 2

You can by adding this to your theme's css file.

style.css

.block-configure,
.block-contentblock-delete { 
  display: none; 
}
