Panes
You can configure the collapsible and resizable pane settings of the Splitter by using JavaScript after the widget has been initialized.
The resize() method of the Splitter recalculates the pane sizes and the split bars are rendered with the current widget settings.
$("#SplitterID").kendoSplitter({
panes: [
{ collapsible: false, resizable: false, size: 100 },
{ }
]
});
var splitterObject = $("#SplitterID").data("kendoSplitter");
splitterObject.options.panes[0].collapsible = true;
splitterObject.options.panes[0].resizable = true;
splitterObject.resize(true);
