Allow only 1 block to be nested within another block

[Ahana Ghosh]

Hi,

I am trying to freeze a blockly code in the Workspace and not allow any insertions/deletions to it except at one location, where only 1 block may be nested.

I have set the following parameters to the blocks in the  Workspace:

- block.setDeletable(false);

- block.setMovable(false);

- block.setEditable(false);

The code is not editable except that: the interface still allows blocks to be inserted in between the code, when taken from the Store in the Workspace. 

I was looking for solutions to stop this from being allowed as well to the code in the Workspace?

Thanks and Regards,

Ahana
