Hello Peter,
I have also the same issue when i set the splitter’s size in percentages it is not fixed with my browser layout.
$(‘#mainSplitter’).jqxSplitter({ width: ‘100%’, height: ‘100%’, panels: [{ size: ‘10%’ }, { size: ‘90%’}] });
$(‘#rightSplitter’).jqxSplitter({ width: ‘90%’, height: ‘100%’, orientation: ‘horizontal’, panels: [{ size: 400, collapsible: false }, { size: 100}] });
