Hide the left [Dashboard list] and right panel [Filter List]

If you are embedding your dashboard in an iframe, you can append &r=false to the url to hide the filter list. When embedding like this the navigation panel should automatically be hidden but if you want to be certain, you can also add &l=false as another parameter. See also the documentation about iFrame embedding.

Presumably, the Embed SDK allows something similar. If you are not embedding, but sharing Dashboards within Sisense proper, you can use a plugin to hide some or all filters. I haven't found a way yet to hide *all* dashboards from view in the nav pane, but you can set up the Jump To Dashboard plugin in such a way that drill dashboards are hidden. So if you set up a starter dashboard through which your users can navigate to the other dashboards, you can hide the other dashboards from the left navigation bar.

(Possibly you can also share the Sisense dashboard using the embedded url -- but that is circumventable by smart enough users :))

Good luck!
