How can you make the splitter collapse on a button click?

Platform: jQuery |
Control: ejSplitter
Tags: general

We can achieve this requirement using the methods “collapse” and “expand” of Splitter control. We can call this methods in any events (for example button click event) in order to expand / collapse the pane of splitter by passing the index value of the required pane.

Please find the below code blocks to achieve the requirement.
