Create filters to assign to templates when adding them to HowNow Online. Users will then be able to use these filters as an option when searching for a template. Filters are an advanced search option that will allow you to group like templates together. 

Templates - Click the + sign next to the filters heading

Type the name of your filter and click save. Optionally you can also assign a filter to a team, so that only members of that team will see the filter and the documents assigned to that filter.  

To rename, delete, edit team assignments or add a sub filter (child filter) right click on the filter and select one of the options.
