Hi d_l,
jqxSplitter can have 2 panels, so you can collapse only 1 panel(left or right for vertical splitter, top or bottom for horizontal splitter). Which panel will be collapsed depends on the value of the “collapsible” property of the first panel – if it is set to false, when the “collapse” method is called, the second panel will be collapsed. Otherwise, the first panel will be collapsed. The “collapse” method can be called either through the API or by clicking the split bar.
