First we need to create a page with a short description (for this exercise only):
Create a page with the projectdoc Blank Document Blueprint
Provide a name and a short description, then check the box to send the document to its homepage
Click 'Create' to see the document in the editor
Click 'Save' at the bottom of the page
The new document looks like this:
Section
title
Add a Space Property
Now add a property to the space homepage.
Open the homepage of your index space
Click 'Edit' to edit the homepage
Add a property named extract-short-description-from-metadata-table and value true (choose hide as a value for the third column, which is called the property control) to the table within the Document Property Marker Macro at the top of the document
Save the homepage
Finally have a look at the test document you created in the index space in the previous step.
The short description is rendered in front of the properties table. The space property extract-short-description-from-metadata-table controls the rendering of every document in the space (or any space that delegates to this space and does not override this property).
projectdoc is picky with the entered values: There must not be any markup for the space property name or value, just the pure text value. Use the Confluence Source Editor Add-on to check the values
