Create new instances (clones) of existing blocks and assign them to regions
Drupal 10 comes by default with a feature that allows you to create new instances of existing blocks and assign those in the theme regions.
- Navigate to Home > Administration > Structure > Block layout
- Locate the region that you wish to populate with your new block
- For this region click on the “Place block” button
- From the list that pops up, locate the block that you wish to place in this region
- You could also use the filter field at the top to quickly search through the available blocks
- Click the “Place block” button at the right of the specific block.
- Configure the block as you would do with any other block
- Save your configuration
Remove blocks from regions
In Drupal 10 in order to remove a block from a region you should just delete it from the regions page. If you need to place the block in the future you could follow the above procedure to create a new instance of this block.
