# orca.ui.start

> A module of morca's API.

Start runs, on a pipeline's Operate tab: the form, its date picker (`orca.ui.coverage`), and the preview of what it would queue (`orca.views.start`), updated as you type.

## Functions

### `start_html`

```mojo
def start_html(mut h: Html, p: PipelineRow, keys: String, rerun: Bool, preview: Optional[StartPreview], keys_per_run: Int)
```

The pipeline page's Start runs section: one range, a backfill (the primary) or one run over it, a preview of what they'd queue, and the same from the command line.
