Hello @Karena ,
Here is complete information about Sidebar.
Example of sidebar on the right side: https://snippet.webix.com/wvmn789t .
There was added property asposition: "right"
As I rightly understood you want other elements on the right side? If it’s true, so I add that Webix Sidebar is a Tree-based component. Sidebar can load data from various sources in different formats. You can find more information in the Loading Data into Tree article. The Sidebar data configuration contains the description of menu items, corresponding icons and sub-items.
So, in other words, the type of sidebar is influenced by data configuration.
