Blocks are the essential elements of Odella workflows. Whether you’re building simple sequences or intricate logic, blocks help bring your workflows to life. Here’s everything you need to know to add, arrange, and customise them.

​
Adding a Block

To add a block, right-click in any empty space on the flow canvas (or press Space) to open the Add Menu.

Search & Select

Start typing to quickly find the block you need in the menu.

Organised by Category

Blocks are grouped by category for easy browsing. Select a block to place it at the location you right-clicked.
For details on all available blocks, check out the Block Reference.

​
Moving Blocks

Repositioning blocks is quick and easy:
  • Drag & Drop: Click and hold the title bar of a block, then drag it to your desired position.

​
Connecting Blocks

Connecting a block (Light Mode)
Connections define the data flow between blocks. Here’s how to link them:

Create Connections

Click and drag from an output port on one block to an input port on another. Outputs are on the right side, inputs are on the left.

Port Rules

Outputs can connect to multiple inputs, but each input can only connect to one output. Ensure data types match for smooth operation.
For more details on port data types, refer to the Block Reference.

​
Disconnecting Blocks

Need to adjust a connection?
  • Move Connection: Click and drag on a connected port to change the connection to a different port.
  • Delete Connection: Drag the connection line to an empty space to remove it.

​
Creating a Subflow

Creating a subflow (Light Mode)
Subflows allow you to group blocks for cleaner, more manageable workflows.
1

Select Blocks

Hold Shift and click on each block you want to include in the subflow.
2

Create Subflow

Right-click one of the selected blocks and choose Create Subflow. This action moves the selected blocks into a new (unsaved!) flow, complete with input and output blocks that link back to the main flow.
Name and describe your subflow in the flow info section to keep it organised. Don’t forget to save with CMD+S or CTRL+S.
The original blocks in the parent flow remain in place, so you’ll need to manually replace them with your subflow if desired.

​
Editing a Block

Editing a block (Light Mode)
To customise a block, click the gear icon in the top-right corner. This opens the Block Editor.

Edit Block Details

Adjust the block’s title and description for clear documentation.

Fine-Tune Settings

Modify settings specific to the block type, such as batch processing or variant options.
