By now, the sidebar is closed after change engine on mobile. This is a bad experience of use. Change this behavior to load the respective engine components without closing the sidebar. Then, sidebar should only be closed if some component is selected.

Suggestion of how to do this:

In the engine-menu, make the engine options buttons instead anchors. So, the navigation that causes the sidebar closing will be solved.

Then, make the components-menu receive the engine selected on the engine-menu by prop and keep watching it to make a re-fetch when it changes.
