How do I archive older posts in my Wix blog?
Make it easier for your visitors to find blog posts from a specific time period with a Blog Archive. Your Blog Archive will automatically gather all of your past posts and categorize them by month and year. You can display the Blog Archive as a list of dates or a drop-down menu.
To add a Blog Archive: From the left side of the Editor, click the Add button > click Blog Elements > click Archive.
Click the archive button that is added to your site > from the pop-up menu, click Settings > customize your archive's layout, date format and number of months to display.
You can currently only customize the date format for the List of Dates layout.
