[xwiki-devs] How to create sub-space in xwiki?

Hi All, i have created a space on xwiki with the name MySpace. Now i want to create one sub space under MySpace with name Releases. When i go MySpace and do add space and give the name of my new sub space i.e Releases . It does not add that space under MySpace but it adds as seperate space together. Is it possible to create sub-space ?
