# Blocks

There are six categories of blocks in GoLess:

* **General**: To conduct a general action within the workflow. For example, make an HTTP request or run another workflow.
* **Browser**: To control the browser.
* **Web Interaction**: To interact with the active tab of the workflow. Prior to using blocks in this category, you should use a New Tab or Active Tab block.
* **Control Flow**: To add logic to the workflow.
* **Online Services**: Services that connect to GoLess.
* **Data**: Change or manage variables or tables of a workflow.

## Block Settings

The blocks are accompanied by a menu and parameters that may be configured.

### Menu

To find the block menu, place your mouse on a block in the editor's canvas, and it will show up above the block.

* **Delete**: remove the block
* **Block settings**: open up current block parameters.
* **Move block to group blocks**: move the block to the Group blocks by dragging and dropping the icon.
* **Enable/disable block**: deactivate block
* **Run**: execute the workflow from the active block.
* **Edit**: access block properties or click twice on the block.

You can also right-click on the block for more menus.

### Settings

The Block settings enable you to set up the block execution, error handling, and how it looks like.

  * **Execute fallback**: when selected, the workflow will resume to the block that connects to the fallback output
  * **Insert data**: insert data into the table or variable
* **Lines**
  * **Select line**: choose the block link to customize
