[Typo3] New Plugin: How to insert a selector box in the BE

[Matthias Kall]

Hi Mischa,

have a look into your ext_tables.php. There probably is a line like:
$TCA["tt_content"]["types"]["list"]["subtypes_excludelist"][$_EXTKEY."_pi1"]="layout,select_key";
This line deactivates the fields layout and select_key.
If you delete this line, you should have the input field for LIST etc.
If you want nice selectors, you need to use flexforms, but this is quite 
a bit more complicated. You should have a look at the docs for this.
