TYPO3 Core

Until TYPO3 6.2 it was possible to define an image for items in a "select" (documentation: https://docs.typo3.org/typo3cms/TCAReference/Reference/Columns/Select/Index.html#items).

This was used e.g., in EXT:ig_ldap_sso_auth to ease the configuration of whether, in a LDAP directory, groups assigned to a user are stored within the user record ("user is member of groups X, Y and Z") or if the corresponding groups hold their users ("group is composed of users A, B, C and D").

Visually, in 6.2:

and in 7:

In short, the problem is that starting with TYPO3 7 LTS, the icon is tiny and only visible for the current selection whereas in 6.2 it was shown full sized under the list and was clickable, which made sense to define icons and eased the configuration a lot by allowing quick selection to be made among a (typically) short list of options.

This example in EXT:ig_ldap_sso_auth shows that the new rendering totally breaks the usefulness of this previous feature.
