How to Prevent Drop Before on Specific Indexes

[onur-ozguzel]

Hi all;

I' ve a question. For example think i' ve an array like this

originalArray = ['A Tile', 'B Tile', 'Checkpoint', 'C Tile'];

And i' m cloning an item from an another array to this array, let name it 'E Tile'.

While draggin & dropping 'E Tile', i don' t want user to drop this new element before 'Checkpoint', meaning before of the index of 2 in the originalArray. User only can drop this item after the 'Checkpoint'.

Is a rule something like this possible? I' ve tried various ways but couldn' t find a proper workaround.
