Clicking on a manufacturer filter button will filter the product list without confirmation of the action.

Remediation Notes

As used in the filter dialog window already, a "Filter anwenden" button could fix this issue, although for the given structure, this might not be the best option.

The buttons should have appropriate accessible names to describe their purpose. See ___ for an example solution. The success criterion says, the change of content or context can be announced prior to making the change. Having the accessible name set properly, would meet this for screen reader users. For other users it would be best to visually indicate by text. E.g., introducing the filter section by a short text:

<section>
  <h2>Geräteliste filtern und sortieren</h2>
  <h3>Filter</h3>
  <p> <!-- Add description -->
  <button> <!-- Filter dialog window -->
  <fieldset> <!-- Checkbox Group for direct filters -->

That description could be:

"Öffnen Sie die gesamten Filteroptionen über einen Klick auf den 'Filter' Button oder klicken sie auf einen der darauffolgenden Hersteller-Buttons, um die Geräteliste entsprechend zu filtern."

Or you could even set a <legend> inside the checkbox group to properly describe their purpose.

Observation Details

Operating the interactive map, the default on page load is an activated accordion item "Mobilfunknetz" in which are three checkboxes (2G, 4G, 5G). It looks like it functions as a "Multiple Selection List". For reference, see BFIT-Bund Handreichung "Accessible design of user interface elements – Multiple Selection List".

When selecting and activating another accordion item, the map's context changes to that item's content, meaning when "Festnetz" item is activated, the Mobilfunknetz content is removed from the map. As the "dropdown" / accordion item itself should not have functionality to change content, but the interactive elements in it should, activating the "dropdown" evokes an unexpected context change. On a page about 5G Mobilfunknetz / Netzausbau, moving to a "Festnetz" map is considered unexpected behaviour.

Remediation Notes

Remediation of this issue might take significant effort. Ideally, the use of more fitting interactive elements helps users to navigate the options in a more predictable way. If "Mobilfunknetz", "Festnetz", and "HotSpot" are exclusive options, using a fitting component, like a singular selection list, a dropdown, or radio button group, would identify the interactive element right away.

There are a few easier ways to remediate but not without potentially "removing" content.

  • Removing Festnetz & HotSpot options from the map

  • Announcing change of context to make it an expected change, which then would not be considered a failure; this could be done by giving the accordion item button an accessible name of "Nur Festnetzausbau anzeigen"

Selecting a device, already selected in another selection input will swap those devices.

  1. Select device A in selection 1

  2. Select device B in selection 2

  3. Select device B in selection 1

  4. Selection 2 will be changed to device A

This change of context happens without announcement. Neither in advance nor after the selection. The unexpected change might confuse users. Especially when compared devices are similar, the change might not even be noticed at all.

Remediation Notes

Ensure, no unexpected change of context occurs. This could be done by disabling already selected devices in or remove them from other selection inputs.
