Menu Trail By Path
This module automatically highlights menu items that match the current page's URL. It's useful for creating nested menu structures without manually adding all content to the menu, and it works with various page types beyond just nodes.
Menu Trail By Path sets the active-trail on menu items according to the current url.
For example if you are at yoursite.com/blog/category1/article1
Menu Items with these paths will get the active-trail class on them and expand accordingly.
blog
blog/category1
blog/category1/article1
This is particularly useful if you want a lot of nodes to appear as children of certain nodes / taxonomy term / views / referenced nodes / etc, but do not want to add them all to the menu. eg. hundreds of blog articles.
Menu Trail By Path is best used in conjunction with Pathauto.
This module is similar to Menutrails (D6) and Menu Position (D7), except no configuration is needed. It uses the path URL to determine the active-trail instead of setting rules for each node type. It also works for non-node pages such as taxonomy term and views. Just enable the module to see the results.
Drupal 8
- Make sure to use a "menu.html.twig" like the classy-theme (or use that as base theme, like bartik does), stable-theme and stark-theme will not add the classes that you propably will expect, see "No active trail class gets added"-issue.
- The module now has some settings for performance optimizations, see release notes for 8.x-1.2
Drupal 7
- can also handle breadcrumb by path
