What is the blend of manual and trigger in GITLAB?

edit

In GitLab, the blend of manual and trigger refers to the ability to combine both manually triggered and automatically triggered (using a webhook) pipelines for a project. This allows for more flexibility and control over the Continuous Integration and Continuous Deployment (CI/CD) process. For example, a developer can manually trigger a pipeline for testing their changes before merging them into the main branch, while production deployments can be automatically triggered when changes are pushed to the main branch. This blend of manual and trigger helps improve software quality and delivery speed.
