> UI - Context Menu Issue
> -----------------------

> Key: NIFI-4324
> URL: https://issues.apache.org/jira/browse/NIFI-4324
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core UI
> Reporter: Matt Gilman
> Assignee: Matt Gilman

>
> If an item in the context menu is a group-item, the sub menu may not trigger
> when 'mouseenter'-ing the item from outside the context menu. This is most
> noticeable when the first menu item is a group-item. It appears the menu item
> 'mouseenter' event is not triggering. If the cursor is already in the context
> menu (ie when the group-item is second in the list for instance) the event
> triggers as expected.
> Root cause of the issue is that when the context menu is hidden, sub menu's
> are hidden instead of removed. So the sub menu works correctly on the first
> attempt but any subsequent attempts will fail because the sub menu is already
> part of the DOM. Proper removal will allow the sub menu to be created
> correctly.
