Hi Jon,
Thanks for your patience.
In our Kanban sample we have override the default icons by changing the font family of the icons from ‘e-icons’ to ‘kanban-priority-icons`. We have designed the icons for Kanban sample by overriding the existing icons.
By default, in our controls the font-family of ‘e-icons’ class will be ‘e-icons’ as shown below.
In our header template sample, we have our customized icons with the `font-family` as ‘kanban-priority-icons` as per the requirement.
The icons shared in the UG are the built-in icons which you can use with the font family as ‘e-icons’. If you want to use icons available in header template sample use the font-family as in the sample. Kindly get back to us if you need any further assistance.
Regards,
Nevitha
