# Component Panel

The **Component Panel** is located on the left side of the modeler. It contains
all the workflow components available for your model, organized by category.

## Searching for components

Use the search field at the top of the panel to filter components by name. The
search is instant -- results update as you type.

## Categories

Components are organized into categories provided by the model owner:

- **Events**: Trigger components that start a workflow (e.g., "Content is created").
- **Actions**: Components that perform work (e.g., "Send email", "Set field value").
- **Conditions**: Components that evaluate true/false for edge routing.
- **Gateways**: Decision points for complex branching.
- **Subprocesses**: References to other workflow models.

Each category can be expanded or collapsed.

## Favorites

Frequently used components appear at the top of each category with a star
indicator and a visual divider. Favorites are configured by the model owner.

!!! note "Context filtering"
    When a workflow context is selected (via the toolbar dropdown), favorites
    are hidden and components appear in plain alphabetical order, showing only
    those relevant to the selected context.

## Adding components

### Drag and drop

Click and hold on a component in the panel, then drag it onto the canvas. A
node will be created at the drop position.

### Quick-add (alternative)

You can also add components using the quick-add buttons that appear when
hovering over nodes or edges on the canvas. See
[Working with Models > Editing](../working-with-models/editing.md) for details.

## Documentation links

Some components include a documentation icon. Click it to view the component's
external documentation in a popup without leaving the modeler.

## Panel resizing

Drag the right edge of the Component Panel to resize it. This is useful when
component names are long and need more horizontal space.
