# Blocks

Blocks are views used to display and manipulate data. In NocoBase, pages, popups and drawers are considered as containers of blocks, and the container is like a canvas in which various blocks can be placed.

Thanks to NocoBase's design of separating data and view, pages carry data through blocks and organize and manage data in different forms according to different block types.

## Structure of blocks

A block consists of three parts.

1. content area: the body of the block
2. action area: various action buttons can be placed to manipulate the block data
3. configuration area: buttons for operating the block configuration

## Block templates

You can save a block as a template, which can be copied or referenced later.

For example, if a form is used for both adding and editing data, then you can save this form as a template and reference it in the Add Data and Edit Data blocks.
