To allow your residents to easily see any updates to the website, a most recent posts section can be a good idea.
If you would like the most recent posts published from a certain category to be displayed in the sidebar, there is a widget you can use to do this.
1. Navigate to the widgets screen by using the Widgets submenu in the Appearance menu.
2. Drag the Category Posts widget from the list on the left to the widget area on the right. Give it a title, select which category you would like posts to appear from, and how many posts to display. Click Save.
