Subject: Fixes keyboard support for Drilldown.
X-Git-Tag: v6.2.4-rc1~47^2~1^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4ace2aec002323df2243f73db948dc600967dfd4;p=thirdparty%2Ffoundation%2Ffoundation-sites.git

Fixes keyboard support for Drilldown.

Added tabindex=0 to the sub-menu parents. Because they have no href attribute they were not focusable.
