[RashmiBal]

Environment Information

• Package version(s): "office-ui-fabric-react": "7.166.1"
• Browser and OS versions: Chrome Win10

Describe the issue:

Ran Accessibility Insights tool on my UI with Dropdown control & got this error locally.
We are using "office-ui-fabric-react": "7.166.1" version.

Actual behavior:

Fast Pass Error Details:
Path
#Dropdown18
Snippet
<div data-is-focusable="true" id="Dropdown18" tabindex="0" role="combobox" aria-haspopup="listbox" aria-expanded="false" aria-label="Modified On From" aria-disabled="false" class="ms-Dropdown dropdown-145">
How to fix
Fix the following:
Required ARIA child role not present: textbox

If I edit HTML in Dev Tools to add role=textbox and title="some title" to this element
<span id="Dropdown18-option" class="ms-Dropdown-title title-146" aria-live="polite" aria-atomic="true">Oldest</span>
it fixes the issue.

DOM created in my application has Error

Expected behavior:

But this error does not repro in your official example that I see on https://developer.microsoft.com/en-us/fluentui#/controls/web/dropdown here is the codepen: https://codepen.io/RV122/pen/WNRyyjZ

DOM created in Official Office Fabric site example does not have Error.

I can confirm that this is a bug and it should probably be fixed.

Hi @RashmiBal, thanks for submitting the issue. After some further research, it looks like this is a false positive on axe-core, the ruleset under accessibility insights. They're working on a fix. See this issue on their repo for more info: dequelabs/axe-core#2505

I would reach out to them for more info. I will go ahead and close this now
