If you want to create a Category there are two available options. The first one is creating a Category that can used again and again. The second method is for creating a special one off Category. '''Method 1.''' * Settings > Calendar * scroll down to 'Categories' section '''To create a new Category:''' * click on 'New' * Give it a suitable name * Select checkbox to 'Use Colour' * Click in the colour checkbox * choose a colour and click on OK * Click on 'OK' to create. '''To Edit a colour of an existing category:''' * Select the category in the list and click on Edit. * Click on the coloured box * choose a colour and click on OK * Click on 'OK' to save. '''Method 2.''' Single use Category In 'Calendar' Click on 'New Event' Category: - click on drop down to see list of current saved categories. At the top of that list is 'Add a new Category' In that text area type name of category and press 'Enter' key on keyboard. That category will now appear in 'Category' text box. If you save the Event and later go back and open it again. In the Category drop down list you will see that name of the special one off category and it will have a tick showing it was selected. But if you then clickon 'New Event' again - that special one off category will not be available. You would need to recreate it. But if you find you need to use it frequently then it's probably a lot easier to create it via Settings > Calendar as mentioned in method 1.
