EasyUI React Layout does not split as resizable

[spider58]

Hello.

I made a react easyui layout which has west-center-east columns.

I want to define East column as splitted and resizable (with center)

How can i do that

Below code does not working.  I can see layout as unresizable

Code:

          <Layout style={{ width: "100%", height: "100%" }}>
          <LayoutPanel region="north" className="p-top">
            <div>North Region</div>
          </LayoutPanel>
          <LayoutPanel region="west" className="p-left">
            <div >West Region</div>
          </LayoutPanel>
          <LayoutPanel region="east" split="true" className="p-right">
            <div>East Region</div>
          </LayoutPanel>
          <LayoutPanel region="center" className="p-center">
            <div>Center Region</div>
          </LayoutPanel>
        </Layout>
