I am not getting colpos displayed in backend.

[ashupatel1990]

I installed below extension:

I have installed successfully but when i add container element column is not displayed in backend.
What am i missing?

Have you added the needed TypoScript in your Template? Without it, you can`t show any colPos..

I've the same Problem there's no {tx_container_grid} or childrenLeft/Right available in Backend on <f:debug>{_all}</f:debug>. I can see the typoscript with data-processors in the TypoScript-Object-Browser so I think it is loaded. But as I read the TypoScript is just for rendering the frontend?

Using TYPO3 10.4.32 and container 2.1.1 (container-example 2.0)

Sooooo, just for all fools like me walking in this trap and don't know why.
I was trying to migrate from EXT:gridelements to EXT:container.....
The EXT:container will show no Columns in the backend as long as the EXT:gridelements is still activated.
Deactivate EXT:gridelements before testing your containers. ;)
