We will use Template 44 as example to demonstrate how to fix elements at the top of a page. The fixed elements will not scroll with the page. So make sure they have background color so they will work on any colors that come under them.
Only text elements, image elements and navigation bars are supported.
First open the template page "template.html" of Template 44. There are three elements at the top of the page, the company logo, a navigation bar and an empty text element with a white background and a border at the bottom that is used as a header at the top and sit under the company logo and the navigation bar. The company logo and the navigation bar are in a mobile group so they will be handled as a whole in mobile layout. The mobile group also has a white background as the empty text element under the logo and the navigation bar will be hidden in mobile layout.
Select these three elements.
Click on this button on the toolbar or select "Arrange" > "Add to Sticky Header" from the main menu.
The following message will be shown to confirm that they are added to a sticky header. Click on the OK button to exit.
If you need to select all the elements that have been added to a sticky header, select "Arrange" > "Select All in Sticky Header" from the main menu.
To remove all the elements from the stick header, select "Arrange" > "Remove From Sticky Header" from the main menu. Now the elements will scroll with the page.
