You don't need to enter the needed gridelements manually :) but half automatically.

  • Add a folder for grid layouts. For example

    • Grid Layouts

  • Create backend layouts (use it only, if your table tx_gridelements_backend_layout is empty!)

    • edit typo3conf/ext/start/ext_tables_static+adt.sql

    • replace 'xyz' with the page id of your folder "backend layouts" from above

    • Copy the SQL statements from the file and paste it into PhpMyAdmin

    • Send the SQL statements

  • Create backend layouts icons

    • Copy the icons to the tx_gridelements folder in uploads:

cp -aR typo3conf/ext/start/Resources/Public/uploads/tx_gridelements/* uploads/tx_gridelements/

Check the content of your folder "backend layouts". It should contain 8 backend layouts.
