Many themes don't have dropdown menus built-in. That includes Drupal's core themes, such as Bartik. Unless you want to make major code changes, it is best to choose a theme that already have dropdowns available. To find out whether a theme does have dropdowns, read the theme's description and documentation on Drupal. If your theme doesn't support dropdowns, we do have a guide to adding a dropdown menu using a module.

If you want dropdown menus, you'll need to arrange your menu links in a parent-child relationship:. Also, edit each menu link and check "Show as expanded". If you don't choose this option, the dropdown link will only show if you are on the page being linked to.

Your dropdowns will not appear unless your menu block is in a block region that supports dropdowns. This is the major change in Drupal 8 in regards to dropdown menus. You must configure your menu block. Join today and get access to 1,'s of books and videos. Sign up today! That post focused on Drupal 7, but some things have changed in Drupal 8.

Choose a theme with dropdowns Before you can use a dropdown menu, choose your theme carefully. Step 2. Drag-and-drop your menu links to that they are in a hierarchy: Also, edit each menu link and check "Show as expanded". Step 3. Click "Demonstrate block regions" You'll now see a layout of your theme's regions. It should be clear where your menu should be placed. In this case, use the "Navigation" region.

About the author. Steve is the founder of OSTraining. Steve's work straddles the line between teaching and web development.JWTs are commonly used for authentication to routes, services, and resources and are digitally signed, which enables secure transmission of information that is verified and trusted. Seen as a more modern approach to authentication, JWTs serve as a robust alternative to traditional authentication models - eliminating the need to pass sessions or credentials repeatedly to the server.

In this post, I outline the benefits of JWTs and its advantages over session-based authentication. It has a dependency on the Key module which should also be enabled. To generate and validate JWTs, a secret key is needed.

On the form:.

Now, we need to tell the JWT module to use the key we just created as the secret. Save the configuration. As of Drupal 8. As a result, whether or not a user has access to an entity via REST depends on their permissions to access that entity. The response will be empty because we are trying to access this resource as an anonymous user and we prevented anonymous users from accessing published nodes for this example :. You should see the JWT displayed when you visit that route:.

If we paste our JWT in the debugger and put in our secret key, we can see a confirmation that our signature has been verified. Skip to main content. Facebook Twitter LinkedIn. This information is Base64Url-encoded.

Signature - used to check the authenticity of the JWT. The signature is crucial in verifying that the sender of the JWT is legitimate and that the message has not been tampered with along the way during transmission. If the message has been tampered with, the signature will not match because it was generated from the original payload data and will be invalid - failing the authentication. JWT vs Session-based authentication JWT do not require session data to be kept on the server to perform authentication.

For applications running on multiple servers, this alleviates the need for sharing session data across the servers. JWT allows for true RESTful services as the communication between the parties is stateless - requiring a valid token to be included in each request. A digitally-signed JWT is created with the secret key.

A JWT is returned that contains information about the client. This JWT should be stored client-side like in localStorage. If the JWT has expired, a new one should be requested. If validated, the response gets returned to the client.

Started to dive into Drupal 8 twig, and what better place to start than from the top: html. The only other time I've seen a placeholder token system like this was with CTools where they create a placeholder in the generated HTML output and then go back later and replace the token with the actual value.

If this is the same concept, why does Drupal core need to do this? The CTools system was ostensibly to get around some core limitations.

In the Drupal cores default Renderer we have placeholders placeholders might attach some additional assets. If we would print the assets in a normal variable it would happen before all the assets have been collected. So what Drupal 8 does is it first renders everything with the normal rendering in the template, then it replaces the placeholders and collects assets from then, and after all that has been done we finally replace the asset placeholders to add the assets to the page.

The issue where this change was introduced is: Move attachment processing to services and per-type response subclasses. And like this change record says this:. You can see at Theme. Later when the page is being rendered the tokens are replaced by the data scripts,styles etc see HtmlResponseAttachmentsProcessor::processAttachments.

You'll send the data along in the URL as a query string. The result will be HTML, so it won't return anything useful to you, but it will properly login via cookie authentication. RESTful authentication means to send authentication with each request because it is stateless. However this is usually not good enough. There is not a stable Drupal 8 module to do so, but the Services module provides methods for creating non-RESTful actions and targeted actions such as "login".

Make sure to enable the GET method. Now you have everything setup, you can start using the service by running this command in the terminal or by using any application for curl requests like: Postman and Restlet clients.

As packages pulled by Composer are updated along with their dependenciesversion compatibility issues can pop up.

The Build Tools Plugin command we used earlier automatically installed Drupal's standard profile in the Dev environment for us. Now that we've installed the Commerce profile, we want that installed instead. Using Terminus, we can run the Drush command site-install which will first clear the database of the Standard profile before installing Commerce. Log in to your Drupal site in the Dev environment.

Here's our Presentations content type. Note that we have an "Entity Reference" link to the speaker. This field is the key to the whole process. Now that we have out content types set up, let's use the Token module to link their data together.

Underneath your Entity Reference field, you'll see the tokens from your Speaker content type. These tokens contain the information that we want to pass on to Presentations. Join today and get access to 1,'s of books and videos. Sign up today! About the author.

In Drupal 7 the code for handling tokens is part of the Drupal core module. Other difference between the Token module for Drupal 6 and the code in Drupal 7 are: In Drupal 7, [node:author] returns the name of the author; [node:author:mail] returns the email address associated with the author of a node, and [node:author:url] returns the URL of the user profile for the node author.

In other words, it is possible to use [node:author:xyz], where "xyz" is one of the tokens returned for a user object. In Drupal 7, there isn't any function that show the list of the available tokens. If a module needs to show the list of available tokens, it must build the list of the tokens itself and show it in the description of a form field; alternatively, it can use the theme function still available in the Token module.
