Tags work like keywords or labels that will help you to categorize your work. They are also a useful source of filtering and can help you boost productivity.
Tags can be used in numerous applications going from CRM, Project, Contacts, Marketing Automation, etc.
On CRM for instance, under CRM ‣ Configuration ‣ Tags you can create new or edit existing ones.
You can also create them on the fly.
Choose specific colors for each tag to help identify them, or Hide in Kanban, simply by clicking on the tag once it is created.
