Categories are like folders in your Google Drive. Create as many categories as you like so you and your team can better find your templates.
To create a category, enter a name in the dedicated section when saving a Template
If the category does not exist a new one will be created. Just hit enter then SAVE
If the category already exists it will be proposed. Choose this category, hit enter then SAVE
You can search your Templates by category in the Templates menu, accessible from the Wizy.io drop down menu at the top right of your Gmail: https://go.wizy.io/#/mytemplate
NB: To edit a template category you first need to edit a template then edit that template category.
You cannot delete a category. The category will not appear if there are no templates under it
