TicketID: 1671602

Environment

• Kendo UI version: 2024.4.1112
• Browser: [all]

 User should have option to display a splitter inside both normal and hierarchical grids so that user can display few columns to the right side of splitter.This helps when there are columns that are dynamically generated

We recently upgrade Kendo UI from version v2019.1.220 to 2019.2.619 and our user base is freaking out because they can't select the text on web pages that use the splitter.

Completely remove a panel from the splitter, e.g. :
$('#container').data('kendoSplitter').removePanel('#somePanel');

Offer the possibility to add a panel

Completely add a panel from the splitter, e.g. : 
$('#container').data('kendoSplitter').addPanel('#somePanel');
