Allow using current switch in a trivalent state (i.e. : true,false,undefined)
Hi everyone,
This enhancement was thoroughly discussed, researched and evaluated by the Dev and UX teams. As a result, we are not planning to implement the 3-state behaviour as a built in functionality for the Switch component. As a general guideline, оur recommendation would be to use the Switch only for 2-state On/Off scenarios and to consider using other components like a DropDownList or an indeterminate Checkbox for more complex ones.
We will update the corresponding Switch documentation sections with concrete recommendations. A great article on the topic can be found here: https://uxplanet.org/checkbox-vs-toggle-switch-7fc6e83f10b8

It would be really useful for grid (and other components too) filtering: Filter by true, false or do not filter.
