The Header Component can be placed at the top of each of your Pages within your app to show your users clearly what Page they are currently on.
It can also be used to create block sections that can be used as links to other Pages of your app. Header components can be block colours or images can be uploaded as seen below.
To use the Header component select the Header component from the Add Component section of the editor.
Next, choose the LAYOUT tab and choose the smallest of the 4 layouts. This will leave room for Components to be added underneath the Header.
In the Design tab you can choose Override Design to make your Header component stand out. Below the TEXT COLOR was set to white and the BACKGROUND COLOR to black using the color picker.
Now you may wish to remove the button and the Subtitle. You can do this within the CONTENT tab by deleting the Subtitle and toggling the Navigation Link setting. This will leave you with a Header at the top of your Page which clearly shows what Page you are on.
