Feat/pin available submaps

Display Available in Submaps buttons and open submap on click.

There is a problem with test for displaying Available in Submaps, because I had to use two seperate datas for displaying these buttons (one is from chemical/drug, where we get list of submaps, and second is from models, where we get name of submaps). The problem is that if we use fixtures for both - data for chemicals and for models, then ids won't be equal.
