Hi there

flow_objects.jpg

I am using Ext 4.2.

I wanted to create the structure using Ext component, something like as shown in the attached image.

Can you please suggest me How can I achieved this?

like

1] Line with Arrow

2] Circle, For that I think we can use split.

3] Position the Objects, One circle above one is down side.
