Users can resize the tiles by dragging their bottom and right-hand side borders or the bottom-right corner. Use the resizable property to determine if the tile can be resized or allow one-direction resizing only.
The possible values are:
'horizontal'—Users can resize the tile only in a horizontal direction by using the right resize handle.
'vertical'—Users can resize the tile only in a vertical direction by using the bottom resize handle.
true(Default)—Users can resize the tile in both horizontal and vertical directions by using the resize handles from the right and bottom sides and bottom-right corner.
false—Users cannot resize the tile.
Extending a tile in the direction of an adjacent tile will push the adjacent tile down on the next row but on the same column-line. Narrowing a tile produces a gap that can be filled by another, if it fits and if it's on the same column-line.
Note: The resizing functionality is enabled by default.
