Rob Fellows updated NIFI-16222:
-------------------------------
Status: Patch Available (was: In Progress)
> UI - Searchable select keyboard navigation broken when options are grouped
> --------------------------------------------------------------------------
>
> Key: NIFI-16222
> URL: https://issues.apache.org/jira/browse/NIFI-16222
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Rob Fellows
> Assignee: Rob Fellows
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> In the UI, the searchable select control supports grouping options (for
> example,
> connector property fields whose allowable values are organized into groups
> such
> as secrets by provider).
> When a searchable select is populated with grouped options, keyboard
> interaction
> is broken even though visual highlighting still moves:
> 1. Arrow Up / Arrow Down moves the highlighted option, but once the highlight
> leaves the currently visible portion of the list, the panel does not scroll
> to keep the highlighted option in view. The highlight continues to move
> off-screen.
> 2. Pressing Enter while an option is highlighted does not select that option.
> The same Enter behavior works for searchable selects that do not use
> groups.
> Ungrouped searchable selects (static allowable values without a group)
> continue
> to support keyboard navigation and Enter selection as expected.
> Steps to reproduce:
> 1. Open a connector configuration/property UI that presents a searchable
> select
> with grouped options (e.g. a secrets / credential-style property whose
> options
> are shown under group headers).
> 2. Open the dropdown and focus the search field.
> 3. Press Arrow Down repeatedly until the highlight moves past the bottom of
> the
> visible list.
> 4. Observe whether the list scrolls to follow the highlight.
> 5. With a lower/group option highlighted, press Enter.
> 6. Observe whether that option is selected and the panel closes
> (single-select).
> Expected:
> - Keyboard navigation keeps the highlighted option in view by scrolling the
> list.
> - Enter selects the currently highlighted option (same as ungrouped searchable
> selects and mouse click).
> Actual:
> - The highlight can move out of the visible area without the list scrolling.
> - Enter does not select the highlighted option when options are grouped.
> Notes:
> - Limited to (or primarily observed with) searchable selects that render
> grouped
> options.
> - Mouse selection of grouped options works.
> - Ungrouped searchable selects are not affected by this keyboard failure mode.
