The Blog Posts content block is a list of partners, pulled in from the partner content type. There are 2 different modes:

• List (pull in all partner items which belong to the tenant your running on)
• Custom selection (pick certain items and render them individually in custom order)
• Preset filtered list (filter blog posts via tags)

The filter navigation can be turned on / off . Filter navigation is the sum of all put attributes on a partner.
Depending the titleHtmlTag selected the title renders either big (h2, h1) or small (h3, h4)
