Currently, the toggle to grid mode is not the same process for all
snippets: some have both the option 'Layout Grid/Cols' and the ability
to toggle on drag but other don't have the option, making it
complicated/impossible to leave the grid mode. Also, the snippets for
which the grid mode has been blocked don't have their move handle
anymore, which prevents them to use the normal drag and drop (it was
hidden because dragging them would toggle the grid mode).
This commit uniformizes the grid mode for all snippets and adds the
move handle back to the ones that cannot use this mode. It also
improves the grid mode of the 'Items' and 'Carousel' snippets.
More precisely:
- All the snippets that are allowed to have the grid mode now have both
the option "Layout Grid/Cols" and the ability to toggle on drag.
- The snippets who cannot toggle the grid mode have the move handle
back but it doesn't toggle on drag and they don't have the option. They
use the "normal" drag and drop.
- The drag and drop has been improved to allow normal columns to go
inside the grids. Indeed, since the drag was previously blocked, this
case could not occur but now that it is possible, it had to be taken
into account.
- The grid mode of the Items snippet has been improved by removing the
"hardcoded" height that was breaking the grid.
- The vertical dropzones of Carousel appearing when dragging inner
content have been removed because they appeared in grid mode and were
breaking it. It is also more logical because now that this snippet has
a column option, vertical dropzones should only appear when dragging a
column.
