I have a 3-column page layout set up right now with a panel in each column. Each panel has a different amount of content, though, so they're all different heights.
Hello there Annie!
Currently, this is only achievable with third party-tools or custom css sheets. There is a feature request for Confluence Cloud that points at this:
What you could do is try Content Formatting for Confluence (a third-party add-on):
The approach is this:
1- Create your page
2- Add the three section in your page
3- Add one DIV macro in each column (The DIV macro is bundled with Content Formatting for Confluence)
4- Insert the panel macro inside each DIV macro
5- Set the size for each DIV
Keep in mind that Content Formatting for Confluence is a paid add-on with a free trial time.
Let us know your thoughts on this!
