I create 3 different custom forms by Administration > Structure > Contact forms area and need to call them in specific template but most of tutorials mentioned to create form programmatically by creating module or modify theme.inc. Is there any way to create a form in Admin panel then call it in twig file like {{ form.<custom_form_machine_name> }} ?

Hi!

I have installed the Field Caption module, and enabled it. I follow the instruction from

https://git.drupalcode.org/project/image_field_caption/blob/HEAD/README.txt

I choose the field format "Image with caption" on the "Manage display" tab for an image field, but I cannot see it when I edit the content type with the image field...What could I am doing wrong?

Thanks in advance!

Good day!
