[ZEPPELIN-1085] Make dropdown menu scrollbar always visible ### What is this PR for? In Zeppelin docs website, there are 4 dropdown menus(Quick Start, Interpreters, Display System and More) in the navbar. Especially **Interpreters** and **More** menu have lots of lists so I made this dropdown menu scrollable in #1004. Originally the scroll bar is shown up when a user is trying to scroll down. That's why it's hard to notice there are more menus in the dropdown menu. See [this issue](https://issues.apache.org/jira/browse/ZEPPELIN-1085). So I made this scroll bar always visible. But only for chrome & safari. Unfortunately, Firefox doesn't support custom scroll bar. See [here](http://stackoverflow.com/questions/18317634/force-visible-scrollbar-in-firefox-on-mac-os-x). In short, it says >There is no way to actually "force" Firefox render the old-style scrollbar >since the default scrollbar used in the system is predefined by the OS itself >(note that you can modify which scrollbar you want in System Preferences). ### What type of PR is it? Improvement ### TODO - [x] : test this in major browsers ### What is the Jira issue? [ZEPPELIN-1085](https://issues.apache.org/jira/browse/ZEPPELIN-1085) ### How should this be tested? [Build the Zeppelin docs website](https://github.com/apache/zeppelin/tree/master/docs#build-documentation) in your local and check the dropdown menu in navbar. The scrollbae has to be shown right after you click **Interpreters** or **More** menu. ### Screenshots (if appropriate) - Before : scrollbar is only shown up when you are trying to scroll up & down  - After : always visible  - In case of IE, you can always see the scrollbar. So it's not a problem originally.  ### Questions: * Does the licenses files need update? no * Is there breaking changes for older versions? no * Does this needs documentation? no Author: AhyoungRyu <fbdkdu...@hanmail.net> Closes #1143 from AhyoungRyu/ZEPPELIN-1085 and squashes the following commits: 4d10883 [AhyoungRyu] Make dropdown menu scrollbar always visible Project: http://git-wip-us.apache.org/repos/asf/zeppelin/repo Commit: http://git-wip-us.apache.org/repos/asf/zeppelin/commit/1ccbd602 Tree: http://git-wip-us.apache.org/repos/asf/zeppelin/tree/1ccbd602 Diff: http://git-wip-us.apache.org/repos/asf/zeppelin/diff/1ccbd602 Branch: refs/heads/master Commit: 1ccbd602a8c486014a1b412d0200d2628c2bc411 Parents: 5556f81 Author: AhyoungRyu <fbdkdu...@hanmail.net> Authored: Thu Jul 7 15:32:28 2016 +0900 Committer: Lee moon soo <m...@apache.org> Committed: Fri Jul 8 22:22:16 2016 -0700 ---------------------------------------------------------------------- docs/assets/themes/zeppelin/css/style.css | 10 ++++++++++ 1 file changed, 10 insertions(+) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/zeppelin/blob/1ccbd602/docs/assets/themes/zeppelin/css/style.css ---------------------------------------------------------------------- diff --git a/docs/assets/themes/zeppelin/css/style.css b/docs/assets/themes/zeppelin/css/style.css index 8ab197c..1a6f3da 100644 --- a/docs/assets/themes/zeppelin/css/style.css +++ b/docs/assets/themes/zeppelin/css/style.css @@ -141,6 +141,16 @@ body { overflow: auto; } +.scrollable-menu::-webkit-scrollbar { + -webkit-appearance: none; + width: 7px; +} + +.scrollable-menu::-webkit-scrollbar-thumb { + border-radius: 3px; + background-color: gray; +} + .index-header { font-size: 16px; font-style: italic;
