Important: A hidden part of the form keeps the preset value 

Description 

The program list applied the Default categories and the Default sorting of the content element only to a request without any selection of the visitor. Once a visitor used the visible part of the form, the part the editor hid lost its preset as well:

• With Hide category filtering switched on and the sorting shown, a visitor who changed the sorting got every program instead of the programs of the default categories.
• With Hide sorting switched on and the category filter shown, a visitor who chose a category got the programs sorted by title, A to Z, instead of by the default sorting.

A part of the form the content element hides now keeps the value of the content element. The sorting of a hidden sorting is always the default sorting, also where a link or a hand-made URL carries another one. The default categories of a hidden category filter always apply. Categories a submission, a link or a hand-made URL carries for such a list are added to them, so they can narrow the list further but never replace a default category. For a part of the form the content element shows, the selection of the visitor applies as before.

Impact 

• A list with a hidden category filter and default categories shows only the programs of those categories, also after the visitor changed the sorting.
• A list with a hidden category filter and no default categories is still filtered by the categories of a link, as before.
• A list with a hidden sorting keeps its default sorting when the visitor filters it.
• An installation that hid the sorting as well to keep the default categories can show the sorting again.
• Behaviour is identical on every supported TYPO3 version.
