The plugin allows you to display list of posts in a variety of ways. You can show them all under links to yearly archives, or you can show them under collapsible years.
If you want to display them under collapsible years, then you need to add <div> and </div> next to the option ‘Before / After (Year headline)’.
Rest of the plugin options are quite self-explanatory. You can set them up according to your needs.
Don’t forget to click on the save changes button to store your settings.
Now to display all your posts on a page, you just need to add
[SimpleYearlyArchive] shortcode to the page of your choice.
