Issue with tabs navigation if there are no second level markdown items #197
Description
Description
While experimenting with the new tabs feature, we encountered an error where the navigation cannot handle the scenario where there are no Markdown files at the second level, but there may be Markdown in the third level.
Expected behavior
I would expect clicking on the Link in the navigation should navigate to the first item in that level.
Actual behavior
Nothing happens when clicking on the Link.
Steps to reproduce the bug
- Assume a pages structure like the following:
pages:
- Home: index.md
- Animals:
- Mammals:
- Kangaroo: 'animals/mammals/kangaroo.md'
- Activate the
tabsfeature:
feature:
tabs: true
-
Preview the site with
mkdocs serve. -
Click on Animals.
-
Observe the page does not change (but note that you can access the page via the Footer!)
Package versions
- Python 2.7.13
