Hi, we need to use the setOptions function when we resize the window, to set the new gantt height.
We also use the "resizable" property.
The problem is, after a "column resize", the inner "option" column width is not set to the object.
So, when we use setOptions, the columns size are back to original.
We found a workaround, where we edit the inner option column size property after a "colunnResize" event, but I think that it's a bug and it should be done by the component itself automatically.
I also tried to keep the "listWidth" by binding the "resize" event of the inner splitbar, but I think it's not a kendo splitter, but a custom spliter made just for the gantt, and it doesn't work.
