Fresh Drupal + UI Suite DaisyUI

Create new entity

• Create a new Block Type
• Re-use body field
• Add title field (text short)
• Add links field (multi valued)

Manage Display :

• Choose default Display Builder
• Goto Display Builder
• Drag Card component on top of the present fields
• Move title field to field slot
• Move body field to text slot
• Move links field to actions
• For links field choose component per items
• Use Button component
• Map Label with field text
• Map URL with field uri
• Pulish

Block Layout:

• Place content block of the new block type in a region
• Contribute and save
• Goto to front or Display Builder
