Drupal 8 form attributes style

Written by David Valdez. Posted on November The Examples module even demonstrates how to create a custom form and display it in a modal window. But what if what you want to do is display an already created form in a modal? How do we do that? Let's see how to do it with an example. Let's display the node add form in a modal window. The first thing that we need to do is create a link which will trigger the modal when the user clicks it. The only special things that this link needs to have are a few attributes that will let Drupal know to display the contents of the link in a dialog:.

And that's it! If you click the link, the form will be displayed in a modal dialog! Drupal will automatically detect that you are sending an AJAX request and will display just the form so you won't need to worry about removing the rest of the blocks or hiding undesired markup. The last thing missing, is what will happen if the user creates a node? By default, the node will redirect the user to another page but if we want to just close the modal dialog and leave the user on the same page we need to tell the form to do that.

For this we are going to alter the form and add an AJAX command letting Drupal know that we want to close the dialog as soon as the node is created. In the. The first function adds an extra submit function which will be executed after Drupal finishes processing the node and the second function adds the command to close the Dialog when the node has been created.

Drupal Answers is a question and answer site for Drupal developers and administrators. It only takes a minute to sign up. So I have a situation where I have a core Link field on a node. I wanted to style that link with custom attributes, so I created a field.

There doesn't appear to be a template or theme hook for the link; given that the core Twig debug functionality doesn't report a child template being invoked. There doesn't appear to be an Attributes object that I could add things into. I'd rather participate in however Drupal is rendering this link directly; or, if it's not extensible, at least know how to replicate what core does.

Answering my own question: the original suggestion was actually a valid solution; the way I had my theme configured meant that the hook wasn't loading. Stupid mistakes!
